Cover and Cut Method and Finite Element Analysis of Comprehensive Transportation in Futian Subway Station
Liu Chang, Zhang Jian, Tan Chuanjiang, Li Boya

Abstract: It is brieftly introduced that the cover and cut method is chosen for the comprehensive transportation hub project facilities in Shenzhen Futian subway station and this structure is simulated with finite element analysis. Taking the impact of stress and deformation of structure from the soil around the construction into account, the spring element is used to simulate the action between the soil and structure in finite element analysis of construction and operation stage, which can get more accurate results and provide a reference for similar projects.
Keywords: underground project; cover and cut method; finite element analysis
