| 摘 要： | 元宝山露天矿3#线长胜排土场是典型的黄土基底排土场，在启用前须对排土场边坡的稳定性进行评价。由于排土场的形成不是瞬间堆积起来的，而是慢慢填筑，综合排土机的作业过程采用刚体极限平衡法对不同排弃高度的边坡进行稳定性计算，并采用FLAC 3D对排土场边坡的变形进行模拟；数值模拟研究了排土场的基底以及地下水等因素对边坡稳定的影响，揭示了边坡的岩体变形、移动规律及滑坡模式，对边坡稳定性做出科学评价，为矿山的安全生产提供依据。

| Abstract: | 3# line Changsheng dump of Yuanbaoshan is a typical loess base dump,before it is employed,the dump slope stability must be evaluated.The formation of the dump is not instantaneous,but is slowly filling up.For the operating process of comprehensive dumping machines,a rigid body limit equilibrium method of different high slope dump is used to calculation slope stability.And FLAC 3D is adopted to simulate the deformation of the dump slope.The numerical simulation studies the impact of the basement and groundwa... |
