水流作用下堆石边坡的稳定分析方法

本文给出了一种考虑重力水流渗透力影响的堆石边坡稳定评价方法．其要点是：求解带有渗透力作用项的土体平衡方程得到边坡的应力分布，在此基础上采用有限元边坡稳定分析方法直接确定最危险滑裂面及相应的抗滑稳定安全系数．文中给出了水流作用下标准堆石边坡及实际堆石坝边坡稳定分析的计算实例

Finite element stability analysis of rockfill slopes under the action of seepage force

A technique for finite element stability assessment of rockfill slopes acted by seepage force is proposed in this paper. The key point is that the stress distribution is determined by solving the coupling equilibrium equations with seepage force taken into account. The potential failure surface and the corresponding safety factor are directly determined by using finite element slope stability analysis method developed by the authors. The illustrative stability analyses of an ideal rockfill slope and a crushed concrete faced rockfill dam are presented in this paper.
