Seismic performance of underground subway station structure considering connection modes and diaphragm wall

Incremental dynamic analysis constitutes the basis of seismic performance evaluation and seismic vulnerability assessment. In this paper, a typical two-story three-span subway station structure is selected as an example structure and its incremental dynamic analysis procedure are presented, including selection of ground motion, intensity measure and limit state determination. The incremental dynamic analysis procedure provided in this study can be a basis for further study on seismic design for underground structural systems.

Station Structure

As separated platform subway station structures are close to the bridge piles, its seismic performance need to be analyzed. An artificial earthquake record is used to analyze seismic performance of the subway station structure. The artificial earthquake record with the Kanai–Tajimi model and trigonometric series superprosition method is generated. It is shown that the influences of the stresses of arch springing and basement are significant under horizontal direction earthquake. Under horizontal direction earthquake, the horizontal stresses of arch springing and basement are 1.46 and 1.61 times than the original stresses and their vertical stresses are 1.34 and 1.59 times than the original stresses. It is shown that the influences of the horizontal stress of soleplate and the vertical stresses of arch springing and basement are significant under vertical direction earthquake. Under vertical direction earthquake, the horizontal stresse of soleplate is 3.30 times than the original stress, while vertical stresses of arch springing and basement are 2.78 and 2.72 times than the original stresses.

This paper mainly deals with the stress and deformation behavior of the subway station structure during the excavation, the construction of the station constructed using top-down method is simulated with ANSYS. The research results show that the diaphragm wall, column and horizontal plate uplift and sink alternately under the influence of foundation rebound, gravity and construction load. Under the influence of lateral soil pressure and horizontal plate, the horizontal deformation curves of the diaphragm wall is similar to bow at first and then to s shape. The huge horizontal stiffness of the plate can control the horizontal deformation of the diaphragm wall effectively. The most disadvantageous positions of internal force in each condition are shown finally, and the results can be referenced by similar engineering.

Station Structure

In view of the seismic weak component of the single-frame-type subway station structure, the three-dimensional (3D) time-domain nonlinear finite element static-dynamic coupling analysis model of interaction between soil and subway station structure is established by, respectively, using rectangular reinforced concrete (RRC) columns, circular reinforced concrete (CRC) columns, and prefabricated concrete-filled steel tube (CFST) columns with a quick-connection device proposed in this article. This analysis model is further used to investigate the influence of different types of middle columns on the seismic response characteristics of the underground structure, such as the interstory displacement angle, seismic damage, and dynamic response. The results show that, compared with the rectangular columns, the circular columns with the equal moment of inertia suffer less damage in the earthquake and have better seismic performance. The prefabricated CFST columns can effectively ensure that the middle columns of the station structure are not severely damaged and can be replaced quickly after the earthquake, which improves the overall seismic performance of the subway station structure and the rapid recovery ability of the structural function after the earthquake.
