The urban river embankment discuss the ecological constructionAnonymous XXXXXXXXAbstract: the urban river embankment construction as the object, discuss the current social background, analyses and compares the river embankment design of traditional methods and characteristics of ecological methods, and puts forward three modes of ecological design and their advantages and disadvantages, and expounds the present situation of the ecological construction in domestic bank and future : the bank; Ecology; Design way; Domestic situationText:A, backgroundRiver Banks part is the amphibious interlaced transition belt, has the remarkable edge effect. Here are active substances, nutrient and energy flow, offer a habitat for a variety of creatures. Natural state Banks often species richness, productivity traditional embankment design often single ?一、背景河流的堤岸部分是水陆交错的过渡地带，具有显著的边缘效应。这里有活跃的物质、养分和能量的流动，为多种生物提供了栖息地。自然状态下的堤岸往往物种丰富、生产力高。传统的堤岸设计往往会单纯从防洪角度出发，采用土堤或者土石混合堆砌起来高高的堤岸。它的优点在于高度的可靠性，结构设计后加起防护堤岸抗流水冲刷能力显著增强。对于洪水暴发频繁、侵蚀严重的区段，这样的设计无可厚非，而对于一般河流堤岸的修建，这样的设计则显得缺乏环境的美化和绿化，同时也破坏许多对生态起重要作用的自然因素，如破坏植被与河床间的联系，造成冲刷侵蚀转移等。另外，河流作为城市风貌不可多得的珍惜资源，也是城市风貌的特色要素，它的景观塑造显得十分必要。同时，堤岸景观建设必然使滨河地区土地价值提升，滨水开发的高投资回报的特点更增强了对城市堤岸景观建设的需求。二、需求——堤岸的生态化建设河流堤岸作为城市中最邻近河流的区域，是城市与河流的衔接线，它的景观规划是提高城市生活品质的需要，也是丰富城市景观的需要。生态化建设，它的根本思路是运用自然本身抗干扰和自我修复的能力来处理人与自然的关系。生态设计方法不同于传统用人工的结构和形式来取代自然的方法，而是用自然的结构和形式来顺应自然的进程。将河岸与河道在生态上联系起来，也就实现了物质、养分、能量的交流：对于生物，它提供了合适的栖息地；植物根系可固着土壤，枝叶可截留雨水，过滤地表迳流，抵抗流水冲刷，从而起到保护堤岸、增加堤岸结构的稳定性、净化水质、涵养水源的作用，而且随着时间的推移，这些作用被不断加强。同时，生态化建设以自然的外貌出现，容易与环境取得协调，造价也较低，不需要长期的维护管理。三、河流堤岸生态化设计方式河流堤岸生态化设计，要遵守生态设计的原则，注重地方性、保护与节约自然资本、让自然做功、显露自然，主要体现在对地域气候环境、河流地质地貌、水文变化的适应，对河流生态环境的考虑，对堤岸地形的处理和对筑堤材料的选择和构造方式方面。1） 人工类：传统方法是采用块石或混凝土块砖等堆砌。可在此基础上加以改进以适应河流景观设计的需求。a) 块石或混凝土块砖干砌，不用砂浆。这样在砌块之间就留有空隙，为后期滨河植物的生长提供了空间。随着时间的推移，堤岸会逐渐呈现出自然的风貌。b) 堤岸采用台阶式分级，台阶面上的空间加以利用，种植植物。当然这两种改进方法对于河岸处现有植被仍存在一定的不良影响，人工痕迹也过于明显。2） 自然类：充分利用堤岸植被原型，可直接将适用于滨河地带生长的植被种植于堤岸上，利用植物的根、茎、叶来稳固堤岸，防止侵蚀、控制沉积的同时也为生物提供了栖息地。3） 人工自然相结合综合了以上两种方法的优点，具有人工结构的稳定性和自然的外貌，见效快、生态效益好，以下为常见的两种类型：a) 种植植物的堆石将由大小不同的石块组成的堆石置于与水接触的土壤表面，再把活体切枝插入石堆中使斜坡更加稳定。根系可提高强度，植被可遮盖石块，使堤岸外貌更加自然。b) 与植物结合使用的插孔式混凝土块将预制的混凝土块以连锁的形式置于岸底的浅渠中，再将植物切枝或植株扦插于混凝土块之间和堤岸上部，其上覆土压实，再播种草本植物。堤岸生态化建设也存在一定的局限性。如：选用的材料及建造方法不同，堤岸的防护能力相差很大，需要运用多学科知识认真分析，这就为设计人员提出了更大的挑战；建造初期若受到强烈干扰，则会影响到以后防护作用的发挥等。这也就对河流堤岸的生态化设计提出了更高的要求。四、国内现状1）省会城市在我国省会城市及计划单列市中有近80％进行了堤岸景观规划。（参考文献[3]）城 市 项目名称 城 市 项目名称北 京 长河城市水系统综合治理 南 宁 堤岸园工程长 沙 湘江风光带 宁 波 滨江大道沿江景观工程成 都 府南河绿化工程 上 海 外滩、陆家嘴滨江大道福 州 闵江江滨公园 沈 阳 浑河观光旅游带广 州 珠江二沙段堤岸景观、芳村长堤建设 太 原 汾河公园贵 阳 南明河景观绿化工程 天 津 海河堤岸改造工程哈尔滨 松花江南岸沿江风景长廊 武 汉 汉口江滩一二期工程昆 明 盘龙江中段滨水生态景观建设 西 安 灞河大水大绿工程兰 州 黄河风情线 重 庆 南滨路滨江旅游观光大道从规划后建成情况看，这些城市河流堤岸景观项目都得到了当地政府与市民的肯定。在这些项目中，堤岸既可成为当地最具吸引力的城市公园，如太原的汾河公园和福州的江滨公园；堤岸也可成为市民日常休闲活动的热点地段，如南宁的堤路园和武汉的汉口江滩工程；堤岸还可成为城市最具特色的地段，如重庆的南滨路滨江旅游观光大道；堤岸更可成为城市旅游的热点，如上海的外滩和陆家嘴滨江大道。总之，经过景观规划的堤岸已成为当地最具特色的地区。从建设效果看，相对堤岸的原来面貌而言，统计资料中的这些景观工程都是较成功的，都成为当地城市关注的热点，成为当地政府的政绩工程，成为当地的民心工程。城市河流堤岸通过景观规划，有效地改善了滨河地段的环境，并带动滨河地段的开发。但必须清醒地认识到，这些城市堤岸景观项目规划并非尽善尽美，也存在这样或那样的问题，仍有待完善。2）中小城市城市经济实力的强大决定了其城市建设水平的高标准和高水平。中小城市河流堤岸景观与统计资料中的城市存在较大的差距，存在更多的问题。特别是由于资金问题，堤岸景观是，纯人工，状态的钢筋混凝土防洪堤，或保持自然防洪状态的土石堤，没有经过景观规划，易造成城市资源的极大浪费。五、前景目前，河流景观建设，特别是城市河流景观建设，在中国正方兴未艾；在发达国家中也是一个久盛不衰的话题。 回顾发达国家河流景观建设的历史，自20世纪70年代以来，随着人们环境意识的普遍增强，重视河流景观的生态功能已成为一个时代的呼唤，河流景观建设的生态设计方法也已得到了空前的重视和发展。他山之石可以攻玉，借鉴发达国家已经形成的成熟的理念和做法，可以使我们少走弯路，搭上隆隆前进的生态建设之车。

Research on the construction safety management of Civil EngineeringIn recent years, the construction accident in civil engineering in our country often occur. This not only caused casualties, also caused great loss of national property, and resulting in a very bad social influence. Therefore, in our country, the construction units in the civil engineering construction projects, shouldstrengthen the construction safety management, all aspects ofsecurity control for engineering, to prevent dangerous accidentsin the end it all. The cause of the civil engineering constructionaccidents are in many aspects. In order to enhance security,should be combined with the characteristics of construction projects and the enterprise's internal and external conditions, the rational allocation of production factors, optimization of management process. In order to realize the construction safetymanagement, construction units should establish a safety management system of a project, it should be carried out from the following aspects:A construction safety consciousness, cultivate the modern safety science theory, occurrence of unsafe human behavior causedcasualties. To implement safety management, it should becombined with psychology, behavioral science to strengthen the education and training of employees in production safety,improve the consciousness of safe production, so as to guide the safety production behavior of employees. For the construction enterprises should strengthen safety awareness and educationproject personnel, developing the regular safety education to the construction personnel involved in the project, and to carry outsecurity work. Three level education to the new participate in the work of the operating personnel; often transform types of employees, should be safety training for new types of work, makeoperation personnel matters needing attention can be familiar with the safe operation of the. In order to make safe productionconsciousness win support among the people, enterprisemanagement personnel but also in engineering project, using a variety of promotional tools to start a variety of education,cultivate the construction personnel safety consciousness. Andin the management of enterprises, the production safety systemthought to. Leaders at all levels and enterprises in issuing the project production task, should also carry out safety productionmeasures. Such as the production safety requirements to the construction personnel, so conducive to safe thought into the production of management, let each employee has consciously in the psychological sense of , the establishment of management system for safety in production in addition to strengthen production safety education and awareness of construction project staff, should alsoestablish a safety management system, protect the system from the construction enterprise safety in production of. In order toavoid the frequent occurrence of sudden accident, the construction enterprise should according to the project, to develop a comprehensive, the system of safety management,and invest the necessary manpower and funds to ensure the implementation of the project. Ensure the production safetyconstruction from the system implementation, the project section of construction enterprises should establish the safety inspectionsystem, and regularly to the project construction of the security check. Make a clear record of project construction process,record the dangerous post, and regularly check the work. Self evaluation and construction team every week to organize asafety activities, the project department to make regular safetyevaluation for project production. Construction enterprises in theconstruction of civil engineering, in order to establish a safety management system, need to make corresponding technical measures for safety management system, a comprehensivescientific standard for , the safety work of construction enterprise project technical measures should be prior to commencement of for engineering and technical measures should be strict examination and approval, the approval before implementation. If the design changes during construction, corresponding safety technical measures should be coordinated with the adjustment,will follow. The safety technical measures enacted personnel andparticipation, should fully understand the project as the construction scheme, construction environment, the actualoperation has, and combined with relevant laws and regulations or the security policy to establish safety technical measures,which can ensure the safety measures. In civil engineering construction of large, corresponding safety technical measuresshould be formulated more comprehensive and more specific,must be carried out through the whole process of construction,and mainly covers to other engineering safety. To establish the system of safety management, construction enterprises should also be strict safety before the construction of the project, technical personnel should to the technical measures for the construction personnelwork. Such as technical personnel issue written materials relatedto the construction personnel, and the implementation of safety technical measures of construction workers to regularly check;when technicians found construction personnel in violation oftechnical measure behavior, to give timely corrected. When theconstruction personnel technical mistakes when amended and supplemented immediately. In order to ensure the safety ofconstruction enterprises to implement, should take theseinspection of production safety measures the formation of rules and regulations, require employees to strictly abide by, so to ensure safety production system. At the same time, the construction enterprises can also follow the specific constructiondevelopment situation, formulate a set of safety technical measures linked to reward and punishment system, to strictly abide by the department or individual production safety, strictsecurity checks to reward, and if there are penalties for violations of the phenomenon. At the same time should have a goodproduction safety supervision work, and sent to the specialized production safety supervision work. When there is potential safety hazard factors in project development, should be timely analysis and inspection and make treatment immediately, so thatthe safety management to implement, implement the specificsystem, ensure the feasibility of production safety. The range ofcivil engineering projects involved in the construction processmore widely, because the factors which affect the engineering safety more. But in the construction process, the occurrence of safety accidents is often unexpected, with occasional andunexpected strong. These come unexpectedly accidents, serious damage often caused casualties and , strengthen the safety production and environment management in civil engineering construction process,environment is an important factor influencing the construction safety. So in order to guarantee safety in production, enterprises should be to strengthen the management of construction site. As in the construction site, the unnecessary equipment and surplus materials, should be timely treatment. In the pile construction materials in order to keep the construction site, the patency of the road accident, ensure to timely rescue, this is to protect the safety measures to realize. And construction enterprises shouldstrictly abide by the rules and regulations, which occurred on theconstruction site of the waste, garbage bag, cement, waste materials and other items should be clear, it can keep the siteclean, to create a civilized construction environment for safe construction. Create a safe production environment construction enterprises, should also be reflected in the risk disposal of equipment. For some such as the construction of electricity,dangerous equipment, cloth rod is used, should by the competent department of enterprise safety approval approval,the approval before they can be put into use after. And in the process of construction of civil engineering, a comprehensive analysis of the conditions of construction project. Some of the effects of environmental factors of the quality of construction, totake timely measures, and to conduct a comprehensivespecification, so that can realize the safe construction quality engineering to create good conditions.

有一篇施工监控的论文，你查收一下吧，希望对你有用！

土木工程的英文是Civil Engineering ,直译是民用工程，它是建造各种工程的统称。它既指建设的对象，即建造在地上，地下，水中的工程设施，也指应用的材料设备和进行的勘测，设计施工，保养，维修等专业技术。土木工程随着人类社会的进步而发展，至今已经演变成为大型综合性的学科，它已经出许多分支，如：建筑工程，铁路工程，道路工程，桥梁工程，特种工程结构，给水排水工程，港口工程，水利工程，环境工程等学科。土木工程共有六个专业：建筑学，城市规划，土木工程，建筑环境与设备工程，给水排水工程和道路桥梁工程。土木工程作为一个重要的基础学科，有其重要的属性：综合性，社会性，实践性，统一性。土木工程为国民经济的发展和人民生活的改善提供了重要的物质技术基础，对众多产业的振兴发挥了促进作用，工程建设是形成固定资产的基本生产过程，因此，建筑业和房地产成为许多国家和地区的经济支柱之一。.古代的土木工程有很长的时间跨度，大致从公元前500年新石器时代出现原始的土木工程活动到16世纪末意大利的文艺复兴，导致土木工程走上迅速发展的道路为止，前后经历了两千多年。在这段时间内，由于科学理论发展及其缓慢，土木工程也没有突破习惯的发展。从17世纪中页开始到20 世纪40年代第二次世界大战结束为止的300年间，国外的建筑取得了长足的进步。土木工程进入了定量分析阶段。一些理论的发展，新材料的出现，新工具的发明，都使土木工程科学日渐完善和成熟。到了近代，二战结束之后，许多国家经济起飞，现代科学日益进步，从而为进一步发展提供了强大的动力和物质基础。人们生活水平的不断提高，必然要求越来越舒适的居住环境，在这种情况下，建筑的发展直接推动了土木工程的发展。总的来说土木工程是一门古老的学科，它已经取得了巨大的成就，未来的土木工程将在人们的生活中占据更重要的地位。地球环境的日益恶化，人口的不断增加，人们为了争取生存，为了争取更舒适的生存环境，必将更加重视土木工程。在不久的将来，一些重大项目将会陆续兴建，插入云霄的摩天大楼，横跨大样的桥梁，更加方便的交通将不是梦想。科技的发展，以及地球不断恶化的环境必将促使土木工程向太空和海洋发展，为人类提供更广阔的生存空间。近年来，工程材料主要是钢筋，混凝土，木材和砖材，在未来，传统材料将得到改观，一些全新的更加适合建筑的材料将问世，尤其是化学合成材料将推动建筑走向更高点。同时，设计方法的精确化，设计工作的自动化，信息和智能话技术的全面引入，将会是人们有一个更加舒适的居住环境。一句话，理论的发展，新材料的出现，计算机的应用，高新技术的引入等都将使土木工程有一个新的飞跃.English is the Civil Engineering Civil Engineering, civil engineering is literally, it is the construction of the project collectively. It means building objects that the construction on the ground, underground, water works facilities, equipment and materials to use in surveying, design construction, maintenance, repair and other professional skills. Civil Engineering with the progress of the human society, has been transformed into large integrated disciplines, it has a number of branches, such as : construction, rail projects, road projects, bridge projects, special project structure, water drainage works, the port project, water, environmental engineering disciplines. A total of six professional Civil Engineering : architecture, urban planning, civil engineering, construction and environmental engineering equipment, water drainage works and road bridge Engineering as an important foundation subjects, its important attribute : an integrated, social, practicality, uniformity. Civil Engineering for the development of the national economy and improve the living standards of the people provided important material and technological foundation for the revitalization of many industries played a catalytic role in the construction of fixed assets is a basic production process, the construction and real estate in many countries and regions become a pillar of the economyAncient Civil Engineering has a long time span, roughly 500 years before Christ from the original date in civil engineering activities to the 16 century Italian Renaissance, resulting in the rapid development of the Civil Engineering on the road today, and has experienced more than 2,000 years. During this period, due to the development of scientific theories and slow, there is no breakthrough in civil engineering from 17 pages to 40 years in the 20th century end of the Second World War 300 years, foreign construction made great strides. Civil Engineering has entered a phase of quantitative analysis. Some theoretical development, the emergence of new materials, new tools of invention, the Civil Engineering Science is perfection and maturity. In modern times, after the end of World War II, many countries economic takeoff, the increasing advances of modern science, so as to provide a powerful impetus to further development and material basis. People's living conditions continue to improve, more and more comfortable living environment for the inevitable in the circumstances, the construction of development directly to the Civil Engineering development.
