  Study on the Working Mechanism of Prefabricated Subway Station Structure under Earthquake

  Abstract: Based on the engineering background of a single-arch large-span prefabricated subway station in Changchun, a three-dimensional numerical model of the fabricated structure and cast-in-place structure considering soil-structure interaction was established. The seismic time history analysis showed that the fabricated structure had excellent resistance to deformation and better mechanical...
