Abstract

In order to study the seismic performance of prefabricated subway station structure (PSSS), the shaking table test was carried out to analyze the seismic response of PSSS. According to the shaking table test results, a three-dimensional finite element model considering the interaction of PSSS, enclosure structure and soil was established. Numerical simulations of the seismic response of PSSS under different test conditions were implemented. Through the comparative analysis of numerical results and shaking table test results, the seismic response characteristics of PSSS were revealed, and the seismic damage mechanism of PSSS was summarized. The results showed that the numerical results and shaking table test results reflected similar regularities, indicating that the established finite element model and analysis method were reliable and effective. PSSS had good performance in earthquake resistance, prefabricated joints had outstanding performance in deformation resistance, which enabled the prefabricated components to work together. Under extreme earthquakes, the vault, the upper and lower ends of the side walls, the internal non-load-bearing structure, and the envelope structure of PSSS were the most severely damaged areas. It was reasonably predicted that the seismic damage mechanism of PSSS is divided into three stages: firstly, the enclosure structure suffered seismic damage; secondly, the non-load-bearing structure inside the structure loses stability; finally, the top arch structure degenerates into a three-hinged arch structure.
