通过对北京大兴线义和庄明挖车站的基坑围护结构的设计,介绍了如何结合地质条件,周边的建筑环境,以及工程造价关系等情况,合理选择围护措施,使围护方案不仅技术上可行,经济上合理,而且简单易实施。同时也介绍了钻孔灌注桩+钢支撑围护方法在地铁车站深基坑围护结构方面的应用,这是目前北京地区应用非常成熟的一种深基坑围护方法。 Through to Beijing line Yihezhuang open excavation station's hole excavated for building foundation building enclosure's design, introduced energetically how to unify the geological condition, the peripheral construction environment, as well as situations and so on building cost of projects relations, choose the surrounding protection measure reasonably, causes in the surrounding protection plan not only technology feasible, in economy reasonable, moreover simple easy to implement. Simultaneously also introduced drill hole filling pile + steel support surrounding protection method in subway station deep hole excavated for building foundation building enclosure aspect application, this is the present Beijing area application very mature one deep hole excavated for building foundation surrounding protection method. 在计算地下工程围护结构内力时,采用了古典的等值梁法。等值梁法模型简单,便于计算,安全性高,在我国工程界有着广泛的应用。对本深基坑工程进行的等值梁法的围护设计计算,可为类似工程的基坑设计计算提供参考。When computation understructure work building enclosure endogenic force, has used the classical equivalent Liang law. The equivalent Liang law model is simple, is advantageous for the computation, the security is high, has the widespread application in our country engineering. Equivalent Liang Fa surrounding protection design calculation which carries on to this deep hole excavated for building foundation project, may provide the reference for the similar project hole excavated for building foundation design calculation.
