摘要: 对支护结构在水土压力作用下的变形及力学行为的全面认识是深基坑支护结构设计取得成功的关键。而实际工程中由于受到各种因素的影响，实测水土压力与理论值存在一定误差，影响到支护结构的安全和稳定性。市民广场站是无锡地区建设的第一批地铁车站，通过该工程实测数据的分析，获得了水土压力随施工过程的变化规律，对该地区后续类似工程设计及施工有一定指导意义。

Abstract: The comprehensive understanding of deformation and mechanical behavior of retaining structures under water-earth pressures is of paramount importance for the design of deep excavations. However, there is a certain error between the measured and theoretical pressures. The error induced by various factors affects the security and stability of retaining structures. The Residential Square Station is a representative project of Wuxi Metro Line 1. The variation law of water-earth pressures during the construction process is studied through the analysis of the measured data. The results have guiding significance for similar projects in Wuxi.
