Analysis of the Dynamic Response Mechanism of Rock Slopes Based on Numerical Simulation

Abstract

Rock slopes are widely distributed in China's strong seismic areas, and due to the wide distribution of seismic areas in China and frequent seismic activities, there is an urgent need to carry out scientific research on the dynamic response of slopes. This paper aims to use the discrete element method to simulate three different earthquake waves on a simplified model and analyse and evaluate the results based on the visual images obtained from the experiment. The results show that the maximum displacement is concentrated at the bottom of the slope model, indicating that the bottom of the slope is most vulnerable to damage under earthquake action. In practical engineering, the state of the construction slope should be monitored in real time to reduce losses caused by earthquakes and other damage. In this study, the effects of different seismic waves on the dynamic response of slopes were investigated to lay the foundation for subsequent studies on the stability of slopes in multi-subsequent earthquakes.
