摘　　要：在深基坑施工过程中,承压水对周边环境及基坑自身影响较大,因此进行相应控制至关重要。结合在建地铁项目,在悬挂帷幕条件下,根据土力学基本原理,按照相关规范标准规定,总结了基坑抽排承压水对周边建构筑物沉降影响的计算方法,相应计算可为软土基坑承压水抽水减压条件下的周边建构筑物沉降计算提供参考。Confined water has a great impact on the surrounding environment and the foundation pit itself during the construction of deep foundation pit,and the corresponding control is very important.In combination with the subway project under construction,under the condition of suspended curtain,the calculation method for the impact of the pumping and drainage of confined water from the foundation pit on the settlement of surrounding buildings is summarized according to the basic principles of soil mechanics and the provisions of relevant specifications and standard.The corresponding calculation can provide reference for the settlement calculation of surrounding buildings under the condition of pumping and depressurization of confined water from the soft soil foundation pit.
