Abstract The Qianhaiwan station of the Shenzhen Metro is located in the reclamation area of Qianhai, which consists of a typical marine mud stratum. The excavation of a foundation pit, envelope controlling, and the stability of the rock surrounding the subway station are key in such complex conditions. The station runs parallel to the integrated, key transportation projects in Qianhaiwan, and interaction may occur among the foundation pits of these projects. Based on the numerical simulation of different foundation pit spaces, excavation sequences, and consolidation, the relationship of foundation pit spaces to the excavation sequence was studied and reasonable values concerning this are given.
