摘要：
Taking waste dump slopes of Tangshan Sanyou Mine for example, this paper simulated the waste dump slopes that under the influence of different accelerated speed peak values with earthquake action by utilizing numerical simulation software Geostudio and analyzed waste dump slopes' stability changes under the influence of earthquake action. According to the result of numerical simulation, with the increases of peak value of earthquake wave accelerated speed, the safety stability coefficient decreases gradually and slopes of waste dump gradually develop from a basic stable state to the unstable state. When peak value of earthquake wave acceleration is smaller than yield acceleration that resulting in the destroy of slopes, the weakening of the earthquake action on the slope stability degree is small. On the contrary, once the peak value of the earthquake wave acceleration is greater than the yield acceleration of the slope, it has a serious impact on the stability of the slope.
