摘　　要：为了评估弃碴场的稳定性,通过实地勘察碴场的现状及堆碴体的物理力学参数,选取堆碴体的典型剖面采用Geo Studio软件进行稳定性评估,分析不同工况条件下堆碴体的边坡及其整体的抗滑稳定性。结果表明:目前堆置状态下的碴场边坡及其整体均处于稳定状态,计算安全系数均大于规范规定的安全系数标准。In order to evaluate the stability of the spoil disposal site,site survey is carried out to investigate the current status of the disposal site and the physical and mechanical parameters of the spoil heap.The typical section of the spoil heap was selected for stability evaluation with Geo Studio,and slope and overall anti-sliding stability of the spoil heap was analyzed under different working conditions.The results show that the slope of the spoil heap and spoil heap itself are in a stable state under current status,and the calculated safety factor is greater than the standard safety factor specified in the specification.
