摘要：
This paper focused on the study of shared diaphragm walls in the foundation pits of Chegongmiao station of Shenzhen subway line 11. During the study, typical tested section was selected, and concrete strain meters were embedded so as to carry out internal force test for diaphragm walls. Stability of the station structure was evaluated. The ABAQUS software was used to analyze it, and shared diaphragm walls were affected greatly by construction of adjacent excavation, and internal forces varied significantly, while other diaphragm walls were affected slightly by construction of adjacent excavation, and the effect could be ignored. In the end, it provides a reference for the construction of subway station in Shenzhen area. © 2017, Editorial Department of Journal of Northeastern University. All right reserved.
