| 摘 要： | 将强度折减技术与快速拉格朗日元法相结合,对某岩质高边坡进行了稳定性分析评价,并与极限平衡法分析结果进行了比较.结果表明,基于强度折减的快速拉格朗日元法不需要假设滑动面形状位置,确定的最危险滑移面是一条具有一定宽度的滑移带,与实际情况极为吻合,它能合理简便地确定边坡的稳定性系数,是进行岩质边坡稳定性评价的有效方法.

| Abstract: | The stability analysis for certain rock slope was performed by combination of the strength reduction technique and fast Lagrangian method.The comparison of the evaluated results with limit equilibrium shows that,with the combined method,it is unnecessary to suppose the shape and the position of the sliding plane of the slope,and that the most dangerous sliding plane is a sliding zone with certain width,which is in agreement with the reality.Therefore,the present method is convenient and reasonable for deter... |
