应用临界滑动场技术确定排土场极限堆高

Determination of Limiting Dump Height with the Critical Sliding Field Technology

边坡临界滑动场技术从边坡与基底整体出发,通过数值计算,快速、准确地确定多层介质边坡任意形状的临界滑动面,全面评价边坡局部和整体稳定性。应用滑动场技术的反向搜寻方法,即给定安全系数,搜寻边坡允许的最大坡角,并结合工程实例选择控制排土场稳定的剖面,进行排土场极限堆高设计。

From the slope to the base,the slope critical sliding field technology is adopted to accurately and quickly determine the critical sliding surface of multi-layer and multi-step slopes with the arbitrary shape after calculation and to give an overall evaluation on the integrated and partial stability of slope.The reserve probe of the critical sliding field technology is carried out,where the safety coefficient is given to seek for the maximum slope angle.In combination with the engineering cases,the paper selected the correct slope face to keep the stability of the dump and design the limiting dump height.
