摘要
以某排土场为背景,在保证边坡稳定性的前提下对排土场堆置参数进行优化设计,利用GEO-STUDIO软件对优化后的排土场进行建模并开展稳定性分析,最终得到最佳的排土场堆置参数。通过Bishop法对典型剖面进行正常、降雨及地震工况下稳定性分析,得出边坡安全系数为1.424、1.306、1.205,均大于1.15,优化参数合理可靠。
Taking a certain dump as the background,the optimal design of stacking parameters of the dump was carried out on the premise of ensuring slope stability.Geo-studio software was used to conduct modeling and stability analysis of the optimized dump,and finally the optimal stacking parameters of the dump were obtained.The Bishop method is used to analyze the stability of the typical section under normal,rainfall and seismic conditions,and the safety factors of the slope are 1.424,1.306 and 1.205,which are all greater than 1.15.The optimized parameters are reasonable and reliable.
