Analysis and Research on Deformation Law of Monitoring in the Whole Process of Deep and Large Foundation Pit Construction
Based on the deep and large foundation pit project of a subway station in Nanjing Metro Line S8,this paper monitored and analyzed the foundation pit excavation,surrounding environment,construction and design requirements for monitoring.According to the monitoring data,the stiffness of surrounding surface and diaphragm wall and the influence range of foundation pit construction on surrounding settlement are analyzed and summarized,which can provide reference for similar deep foundation pit projects in the future.
