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。
A comprehensive understanding of the deformation and mechanical behavior of the supporting structure under the action of soil-water pressure is the key to the successful design of the retaining structure of the deep foundation pit. However, due to the influence of various factors in the actual project, there is a certain error between the measured water and earth pressure and the theoretical value, which affects the safety and stability of the supporting structure. Civic Square Station is the first batch of metro stations built in Wuxi. Through the analysis of the measured data of the project, the variation regularity of water and earth pressure with the construction process is obtained, which is of guiding significance to the subsequent similar project design and construction in this area.
