Abstract

As metro and urban light railway transit projects are rapidly launched in China, land exploitation projects along the railway are increasing too, and lots of new buildings’ deep foundation pit work are located around metro station and tunnel protection sphere, the metro station will inevitably be influenced by those engineering constructions. Based on a deep excavation project around the metro tunnel in Wuhan, using Midas GTS software 3d numerical analysis model of deep foundation pit excavation, the simulation results show that tunnel structural maximum displacement occurs in the bottom of foundation pit excavation. It is suggested that foundation pit supporting design should be strengthened in frequency of encryption and monitoring, especially the horizontal displacement of retaining structure, supporting structure internal force and deflection.
