Taking some foundation pit project of huadian group huazhong headquarters R&D base adjacent to the Wuhan Yangtze River tunnel as the research object, the finite element analysis software MIDAS/GTS NX of rock and soil structure was used to simulate the nine construction conditions during the construction of the foundation pit. The deformation of formation, diaphragm wall, and tunnel after the completion of the foundation pit excavation and the tunnel stress before and after foundation pit excavation, were obtained and analyzed. The results show that it was reasonable and feasible to establish the model; the foundation pit excavation and support soil produced the soil displacement outside the pit which caused the maximum 4.17mm horizontal displacement of the tunnel near the foundation pit; the stress value of the tunnel and the change before the excavation of the foundation pit were not significant and within the safe range.
