Abstract

The frequent occurrences of earthquakes often pose serious threats to the stability of geological engineering structures in the affected areas. This article takes the Pusaxi side slope in Sichuan Province as an example, this study utilizes Geo-studio numerical simulation software to conduct comprehensive dynamic response analysis of slopes. The research aims to investigate the dynamic response patterns and stability of slopes under seismic actions. Parameters such as displacement, velocity, acceleration, and acceleration amplification factor are analyzed to determine the dynamic response of slopes. The study reveals that the displacement response of slopes correlates positively with the amplitude of seismic waves. Acceleration response indicates that the bottom of the slope tends to fail earlier than the upper parts under earthquake conditions. Internal dynamic responses of slopes exhibit elevation amplification effects and slope surface amplification effects. Analysis of displacement, velocity, acceleration, and acceleration amplification factor shows that the strongest dynamic response of slopes occurs at approximately half the elevation of the slope surface. Stability calculations using Newmark permanent displacement suggest that slopes are prone to failure when earthquakes exceed magnitude 5.
