Taking the deep foundation pit project of Wuhan World Trade Center(ICC)as an example,the deformation state of the foundation pit and its influence on the adjacent subway tunnel were evalu-ated by analyzing the real-time monitoring data on site.A numerical model was established by u-sing MIDAS/GTS NX software,and the numerical simulation study on the excavation and support process of the foundation pit and its influence on the adjacent subway tunnel was systematically carried out.The results showed that the numerical simulation analysis using MIDAS/GTS NX soft-ware was highly consistent with the field monitoring data,and could accurately reflect the deformation law of soil and surrounding buildings during excavation.Therefore,this study provides valuable practical experience for similar deep foundation pit stability analysis and solves a series of practical problems.
