| Abstract: | Combined on the foundation pit engineering of a residential building project in Shanghai,the large-scale geotechnical analysis software Plaxis-2D is used to carry out numerical analysis of the entire excavation process.According to the results of the numerical simulation,the stress and deformation of the foundation pit support structure system and the influence of foundation pit excavation on the surrounding environment are analyzed.The results show that the relevant indicators are within the control range required by code,and the adopted support stmcture can effectively control the influence on the surrounding environment in the process of foundation pit excavation. |

| Keywords: | narrow space foundation pit excavation surrounding environment support structure Plaxis-2D analysis |
