Although many scholars have made more studies on the stability of the retaining structure of foundation pit engineering, the regional differences of foundation pit engineering are very obvious. The soil layers in each region have their own characteristics, and the stability of foundation pit under different strata presents different forms of expression. The stability of foundation pit retaining structure under the condition of soil characteristics in soft soil area deserves further study. Based on the collected some basic foundation pit investigation report and nanjing and the surrounding areas, on the basis of actual engineering statistics, aiming at nanjing it the hongqiao street south XiYing Village 2017 g70 plot to study the stability of foundation pit supporting structure, and the supporting of foundation pit supporting structure in related stability reliability analysis, to the stability of foundation pit in soft soil area structure and deformation problem for further exploration, for the design of foundation pit in soft soil area and the subsequent construction to provide certain reference and technical support.
