Abstract：Based on subway station deep foundation pit project in Nanchang city，in-situ monitoring data of the retaining structure deformation in the foundation pit are analyzed. The laws of the horizontal deformation of the retaining structure changing with excavation depth and time are studied；and the influential effects of groundwater on project are introduced concisely. At the same time，the three-dimensional finite element model of the second excavation zone is established by ABAQUS to simulate excavation of deep foundation pit of subway station. Comparative analysis of calculation and monitoring results of the retaining structure shows that，based on the characteristics of watery ground，the design of retaining structure of subway station deep foundation pit is safe and reasonable in Nanchang city. Composite structure of fender piles and support can control the soil deformation effectively in deep foundation pit of subway station.
