Seismic Response and Spatial Effect Analysis of Large Cross Interchange Metro Station Structure
Since the transfer subway station structure plays an important role in the underground traffic network, and it has the characteristics of complex structure and three-dimensional irregularity with respect to the single subway station, it is a typical spatial structure and cannot be analyzed by a plane model. It is necessary to discuss the seismic performance of large cross-transfer stations. Based on a large cross-change subway station, three-dimensional finite element models of free-field, single-unit subway station and cross-change subway station are established, respectively, and the two metro stations and their surrounding soils are calculated under different ground motion types and amplitudes. Dynamic response, comparative analysis of the difference between the seismic performance of the single station and the transfer station structure and the influence range of the transfer station space effect. The results show that: (1) Compared with the single station, the acceleration response and relative displacement of the transfer station structure and its surrounding soil are smaller than that of the single station, indicating that its overall seismic performance is better than that of the single station; (2) The space effect of the transfer station is less affected by the input direction of the ground motion. The influence range of the end wall is B, and the influence range of the cross transfer node is 3B/2 (B is the structure width). The research results of the thesis have certain reference significance for the seismic design of the transfer station structure.
