Seismic Analysis of RC Subway Station Structures Using Finite Element Method

t constitutes a common problem that deep foundation exerts negative influences on adjacent underground structures. The Chegongmiao subway station is adjacent to the first subway of Shenzhen and Fengshengding shopping street, which is on the planning construction of Shenzhen 11th subway. Based on the finite element method, the paper is investigated to efficiently simulate the effect of the deep foundation on the adjacent underground structures. The engineering measures to reduce the influence of construction are supported for determine the construction plan.

Using dynamic elastic-plastic finite element method, on the base of works together and interaction between loess and flexible retaining wall, 3-D nonlinear FEM (ADINA) is used to analyze and discussed the dynamic response of slope protected by soil nailing retaining wall under the EL-Centro and man-made Lanzhou accelerogram. A model that is capable of simulating the nonlinear static and dynamic elastic-plastic behavior of soil is used to model the soil, and a bilinear elastic-plastic model that has hardening behavior is used to model the soil nailing. Friction-element is employed to describe the soil-structure interaction behavior.The results show that the method is safe and credible. The results of the FEM dynamic analysis can be a useful reference for engineers of the design and construction of the soil nailed wall.
