Abstract

Prefabricated station can effectively improve the quality and efficiency of engineering construction, which is the inevitable trend of high-quality development of urban rail transit. In this paper, a static model test of an assembled metro station is conducted in the context of the first new assembled station of Shenzhen metro with a new C-H-C joint. The finite element model of prefabricated subway station frame is established according to the static model test of prefabricated subway station joint. The nonlinear characteristics of C-H-C joint were described by spring-solid contact, and the nonlinear spring was used to simulate soil-structure interaction, and the finite element analysis model of stratiform-structure nonlinear interaction was established. The static response of the structure under different test conditions was numerically simulated. Test results indicate that the mechanical responses of the physical model and the numerical model were consistent, then, the rationality of numerical model was verified. Compared with the low water level condition, the internal forces and deformation of the bottom slab were significantly amplified in the high-water level condition, and the bottom plate should be designed as beam-columns. The internal forces are mainly transmitted through the joints at the top and bottom corner, and the amplitudes are mainly affected by the contact area.
