Complex geological conditions and confined underwater is of deep foundation construction in soft soil. It is very difficulty to built deep foundation. In light of project practice, the article is focus on introduce underground-diagraph, pressure-relief of confined water, deep foundation excavation, monitor and measurement technology of deep foundation, especially with the focus on discussing operate of pressure-relief of confined water and control methods of settlement.%某地铁站深基坑位于软土层、富含承压水和地下水地段,地质条件复杂,在如此条件下修建深基坑难度很大.介绍该软土深基坑稳定施工技术,主要包括地下连续墙施工、基坑承压水降水、深基坑开挖、监控量测等,着重论述了实际施工中承压水减压的情况及相应的地表沉降控制方法.
