Abstract
本发明公开了一种基于数值模拟的煤矿边坡稳定性分析方法，包括：通过现场勘察点位采集岩土体强度和渗透性数据，采用统计分析方法进行处理，获得初始参数统计特征，模拟岩土体在三维空间内的参数随机分布，得到非均质参数分布场；采用有限元分析方法计算边坡在外部荷载和水文条件下的应力应变响应，确定局部应力集中区域，获得边坡稳定性指标；针对边坡稳定性指标超出范围的区域，获取对应参数分布场的局部偏差值，通过迭代算法调整偏差值，确定优化后的参数分布场；基于优化后的参数分布场重新进行有限元分析，判断潜在失稳点的分布位置，根据潜在失稳点的分布位置确定最终风险边界。本发明提升了边坡稳定性评估的科学性与可靠性。
