摘要: HH-SLOPE软件包括瑞典法、简化毕肖普法和推力传递法等多种极限平衡法,应用该软件分别计算排土场在不同台阶高度和平台宽度下的边坡稳定性安全系数,并运用MATLAB软件对台阶高度和安全系数及平台宽度和安全系数进行回归计算,逐步优化排土场的堆置要素。在保证边坡安全的情况下,尽可能地增加排土场的容积。

Abstract: HH-SLOPE software includes various limit equilibrium methods, such as Fellenius, Simplified Bishop and Thrust Transmission Method etc. It is applied to calculate the safety coefficients of slop stability at different step height and different platform width of waste dump. Regression calculation between step height and safety coefficient and between platform width and safety is acquired by applying MATLAB software, and heap parameters of waste dump are optimized step by step. On the premise of ensuring the slope safety, the volume of dump waste increases as far as possible.
