摘要
通过福州金山某工程利用管井降水实现深基坑放坡开挖的实例,详细论述砂性土场地降水设计与施工的关键问题,着重指出校准土的渗透系数值的关键作用,并分析降水中若干问题和提出解决方法。
An engineering in Jinshan, Fuzhou, where the deep foundation pit is excavated in open after dewatering through well, is introduced. The key problem in dewatering design and construction, in sand field is explained carefully. The importance of correcting the value of the coefficient of permeability is pointed out. Some problems in dewatering are analysed and the solution is suggested.
