苏州地铁盘蠡路车站深基坑降水设计

Station Deep Foundation Pit Dewatering Design of Panli Road Station of Suzhou Metro

基坑降水是地铁车站深基坑工程的重要组成部分,文章以苏州地铁盘蠡路车站深基坑降水工程为例,结合工程的工程地质、水文地质条件和周围建筑物情况,设计了基坑降水方案,并通过建立模型预估了基坑降水效果,而后通过基坑周边地基沉降计算进一步证实了降水方案的可行性。

Foundation pit dewatering is an important measure of metro station deep excavation engineering. Taking the dewatering engineering work of deep foundation pit in Suzhou metro Panlilu station as an example, based on the engineering geological and hydrogeological conditions and the surrounding buildings, the paper discuses the design of the foundation pit dewatering scheme, and the establishment of a model to estimate the effect of foundation pit dewatering measures. It further confirms the feasibility of the scheme after having the calculation of foundation settlement of excavation pit surrounding.
