Abstract
Based on a deep foundation pit engineering of subway station in Ningbo soft soil area, the whole process of excavation of deep foundation pit engineering is carried out by PLAXIS finite element software and comparative analysis with field monitoring data based on HS soil hardening model. The analytical results indicates that the numerical simulation results can be well fitted to the field monitoring data. It is proved that the PLAXIS HS model can well complete the numerical simulation analysis of complex foundation pit excavation in soft soil area. From the Monitoring data and calculated values, the horizontal displacement of the grounding wall and surface settlement caused by the excavation of the auxiliary foundation pit are small, which has little effect on the main foundation pit. It is proved that the foundation pit support mode and construction method used in this project can well control the influence of the excavation of the auxiliary foundation pit on the main foundation pit.
