本文针对城市水利工程基坑开挖空间受限的问题，结合长三角地区某城市排涝泵站工程基坑工程，对城市狭窄空间复杂条件下的基坑围护结构进行了详细研究，探索出一套行之有效的钢板桩加钢管撑对撑相结合的基坑围护方法，并根据理论计算结果对设计方案进行优化调整，用于工程实践，取得了良好效果。该方法解决了在城市有限空间上的围护结构设计和施工问题，为类似工程的设计和施工提供参考。

In order to solve the problem of urban water conservancy engineering foundation pit excavation space con?striction,we investigated the foundation pit retaining structure under complex conditions of urban narrow space in detail,referring to an urban drainage pumping station engineering excavation of the Yangtze River Delta region. We explored a set of effective pit maintainance methods of steel sheet pile with steel pipe support,which achieved good results. We also optimized and adjusted the design scheme according to the theoretical arithmetic. The methods solved the problem of design and construction of retaining structure in the city of limited space,providing reference for the design and construction of similar engineerings.
