Dynamic Response Analysis of Dowel-Slot Grouting Assembly Station under earthquake action

 In order to study the seismic performance of Dowel-Slot Grouting Assembly Station, the displacement and stress changes of the station and the cast-in-place station under horizontal, vertical and horizontal-vertical coupled earthquakes were compared by the finite element numerical simulation method based on a subway station in Changchun. The results indicate that the two stations have the same stress concentration position and the same weak point under different seismic actions, and both meet the aseismic requirements. Compared with the traditional cast-in-place station, the assembly station has obvious advantages in vertical seismic performance, but the horizontal seismic ability is relatively weak, and the difference of the displacement Angle between layers is 20%~60%. Compared with the difference of 46.43% in the maximum seismic stress and 28.51% in the vertical seismic time, the difference of 58.02% in the coupled seismic action shows that the stress concentration is more obvious. It provides reference for further optimization of assembly station.
