Seismic Response Analysis of Bridge Pile Foundations in Saline Frozen Soil Sites

This article studies the seismic simulation analysis of bridge pile foundations in saline frozen soil sites, focusing on the acceleration time history and peak acceleration amplification coefficient of the foundation soil and bridge pile foundations. From the perspective of dynamic analysis, the seismic response of the site and bridge structure is studied, and the following conclusions are drawn: the seismic response of the foundation soil and bridge pile foundations is different, and the seismic response of the bridge pile foundation is relatively obvious, The analysis of the peak acceleration amplification coefficient also confirms this rule. In subsequent seismic research, the focus should be on seismic analysis of bridge structures.
