Spring river 蕴藏 abundant water power resources, among them piece the main purpose for valley segment suitable forly fixing set upping the water conservancy vital point, water conservancy vital point is a flood control to generate electricity.
This text combination piece valley geography geology characteristics, hydrology characteristic, as to it's the water conservancy vital point proceeds first step design.The design, vital point of basic data, main building that main contents include the vital point of a valley water conservancy arranges the project, foundation to handle and start construction the 导s to cut the 流 etc. the contents.
Under the consideration the every kind of factor, choice B - B conduct and actions this vital point the engineering's 坝 stalk line, on the choice of the 坝 type, the right every kind of 坝 type proceeds 优 weakness the comparison is after, and join together this engineering of when ground characteristics, chose the concrete entity gravity the 坝 to be used as this water conservancy the vital point's 坝 type.The 调洪 calculates the adoption the method of widespread half illustrated manual table, at the project that compare three 调洪s the project after make sured a fit, get its design flood is 306.3 rices, 校核 flood 307.1 rice, certain 坝 crest high 程 is 310.9 rice.The main building of this vital point be leak watered by 挡 water building, building, generate electricity the building, put the 空 building to constitute.Pass machine-readable( gravity 坝 stability with should dint calculation procedure) with should dint and stability than the 核 is after, and have to out not 溢流 the 坝 's breadth of economic section, 坝 crest 12.5 rice, high 125.9 rice;Leak water practical WES curve, 消 of curve adoption of the 流 's way, 坝 crest of watch bore 溢 of building adoption can the way adopt the 挑流消 can;Factory premises 坝 the segment include the segment of three machine sets with the segment of a gearing field, factory premises adoption after the 坝 type;The deep bore conduct and actions of adoption puts the 空 building, bore figure to choose to use to have no to press the 坝 inside to sluiceway.Finally start construction the 导流 choose to use the 导流 of two two pieceses the method, be designed spring river piece valley water conservancy vital point gave out aly completely by tie the narrow river bed 泄 the 流 , second periods are from the 导流 bottom bore 泄流 , project.

The book sticks to the West江惠东Dam Project Environmental Impact Assessment Report (Graduation Project version. Because of conditions, as a reference book compiled from large amounts of data, data used in monitoring non-author). Report on the use of the general pattern of the EIA report, based on general, regional overview of engineering analysis environment, the status quo of environmental quality monitoring and evaluation, environmental impact prediction and evaluation of pollutant control measures, site selection analysis of a reasonable, clean production and the total control analysis, public participation, environmental impact of economic profit and loss analysis, environmental management and monitoring and analysis, conclusions and recommendations prepared by the order of the preparation 。Listed by the EIA is based on the use of, in principle, the evaluation factors, work such as grading and evaluation criteria, introduced hydraulic engineering related to natural, social and ecological overview of the project carried out a detailed analysis. The state of the environment through the project's monitoring and evaluation, found that apart from the part of river basin water environment over some indicators, the work environment in the vicinity of the targets to achieve the basic requirements of relevant standards; through the forecast engineering environment, although some factors do not meet standards However, some measures taken to meet the basic requirements - this book lists some of the pollutants prevention and control measures.According to do the work of the spirit of the EIA, the book also had total control of cleaner production and analysis, public participation in the work of the projects carried out environmental impact analysis of economic profit and loss. Finally, the EIA and gives a summary of recommendations and concluded: "This project meets the overall river basin planning, site selection and reasonable efficiency is obvious that environmental damage is limited. So from the point of view of environmental protection, water conservancy江惠东West branch Project construction is feasible. "
