为了揭示排土场边坡的变形与破坏规律,通过现场工程地质钻探方法,初步掌握地层及软弱岩层分布规律。通过室内科学试验方法,准确掌握岩层的物理力学指标。在此基础之上,运用理论分析及FLAC~(3D)数值模拟方法对排土场边坡的变形与破坏进行了科学的研究。得出了排土场边坡内部应力及位移分布特征和排土场边坡变形及破坏规律;运用强度折减法确定排土场边坡的安全储备系数。
In order to reveal the deformation and failure rules of the dump slope, the distribution rules of stratum and soft rock formation are preliminarily obtained through on-site engineering geological drilling method. Through the indoor scientific test methods, accurately grasp the physical and mechanical indicators of rock formation. On this basis, the deformation and failure of the dump slope are studied by theoretical analysis and FLAC 3D numerical simulation. The internal stress and displacement distribution characteristics of the dump slope and the deformation and failure rules of the dump slope are obtained. The safety margin of the dump slope is determined by the strength reduction method.
