| 中文摘要: |
| 在二维条件下，采用极限平衡法分析排土场安全稳定性，创新性地将二维条件下的极限平衡法分析结果，简单地转换为可描述三维整体环境中的排土场安全稳定性，采用Monte-Carlo随机抽样方法对鞍钢集团齐大山铁矿风水沟排土场岩体强度的随机分布参数进行了研究，对排土场边坡破坏的风险进行了评价。 |
| 英文摘要: |
| Under the two-dimensional condition, the limit equilibrium method is applied to analyze the safety and stability of the dump, and innovatively transform the analysis results of the limit equilibrium method under two-dimensional condition to a simple description of the safety and stability of the dump in the three-dimensional whole environment. The random distribution parameters of rock mass strength in geomantic ditch dump of Qi Dashan iron mine in Ansteel Mining were studied by Monte-Carlo random sampling method, and the risk of dump slope failure was evaluated. |
