摘要
已知某露天开采矿坑岩质边坡的工程地质条件以及基本特征,在此基础上运用二维离散元数值分析方法模拟该岩质边坡在开挖后坡体内岩体的应力分布及变形特征,从而对岩质边坡的稳定性状况作出评价。数值分析结果表明,边坡在天然状态下是稳定的,开挖后,斜坡体只是局部浅表层的岩体沿着结构面有滑动,并没有发生整体失稳现象。
On the basis of having known the engineering geological conditions and basic characteristics of rock slope ,in this paper simulates stress distribution and deformation characteristics of this rock slope after excavation by two-dimensional discrete element method to estimate the stability of this rock slope. The numerical results show that the slope is stable under natural conditions, and only the local surface rock slope will slide along structural flat, and will not produce the whole sliding after excavation.
