摘要

以汉口某基坑为例，简要介绍了其支护、止水设计情况以及基坑的运行过程。在此基础上，针对基坑运行过程中出现的涌水涌砂现象进行了原因分析，并有针对性的采取了排水管排水及双液灌浆等疏堵结合处治措施，解决了水患，保证了基坑的正常运行。最后通过这个实例，简述了深井降水和垂直止水帷幕设计中要注意的一些问题。

Abstract

Taking a building foundation pit in Hankou for example

the design of retaining and protecting works for foundation excavation and ground controlling is introduced briefly. During the operation

sand and water gush into the foundation pit from its side and bottom. In order to settle the trouble of groundwater

the reasons are analyzed. And the step of opening up and blocking water is adopted. Good results are obtained. Finally

through this example

some noticeable questions about lowering groundwater of deep well and vertical curtain for cutting off water are expounded.
