Research Status and Prospect of Seismic Test of the Bridge Pile Foundation in Frozen Soil Region
This paper provides a comprehensive overview of the current research on seismic testing of bridge pile founda-tions in the frozen soil region.The purpose,advantages,design,and shortcomings of the frozen soil triaxial com-pression test,the pile-frozen soil system pseudo-static test,and the seismic simulation shaking table test are sys-tematically summarized and analyzed;corresponding improvement measures and development directions are pro-posed.Considering the challenges associated with implementing the interaction system between the bridge pile foun-dations and the frozen soil in laboratory experiments,the idea of utilizing the substructure test method to conduct seismic testing of bridges in the frozen soil regions is proposed.
