Abstract:The dynamic response of a waste dump slope caused by an earthquake is one of the main causes of instability in the waste dump. This article takes the waste dump slope of a certain mine as the background and uses Geostudio software to simulate and analyze the particle displacement time history curve, particle strain time history curve, and safety factor time history curve of a waste dump slope under the action of a magnitude VIII earthquake. The research results indicate that during the period of seismic force action, the maximum particle displacement and maximum particle strain of the slope of the mining waste dump are only 8cm and 0.0025, and the minimum safety factor is 1.65, which is greater than the specified allowable safety factor of 1.10, indicating that the slope of the waste dump is in a stable state.
