The seismic performance of anchor anti-slide pile is strong, however, dynamic research data on this topic are scarce.The pseudo-static method，time-travel analysis method，and strength reduction dynamic analysis method were adopted to study the dynamic stability of this support form through an actual project conducted at a railway station in Dali.This study describes the entire application process and reveals the differences in these methods.In addition，the dynamic stability of this slope and the seismic performance were studied to ensure the safety of this slope.These research results can provide a reference for similar projects.
