中文摘要：
为了研究露天矿压帮内排对端帮边坡稳定性的积极效应，揭示内排台阶参数与端帮边坡稳定性系数之间的函数关系，按照内排台阶的动态发展规律，利用Bishop法对压帮后边坡的稳定性进行分析；采用GEO—slope工程软件，对不同压帮状态下的露天矿边坡稳定性进行数值模拟，通过模拟压帮内排可以使端帮边坡稳定系数从1．027提升到1．455。研究结果表明内排台阶参数与边坡稳定性之间服从指数分布关系。
英文摘要：
In order to study the positive effects on the end slope stability caused by inner dumping with burying slope and to reveal the functional relationship between the slope stability and the bench parameter of inner dumping, this paper utilizes the Bishop methodology to analyze the slope stability after the inner dumping with burying slope according to the dynamic law of inner dump benches. With the help of the engineering software GEO-slope, a numerical simulation of open pit slope stability under different pressure is made to develop the inner dumping with burying slope, which can enhance the end-slope stability coefficient from 1. 027 to 1. 455. The research results illustrate that the exponen-tial distribution relationship exists between inner dumping bench parameters and slope stability.
