摘要
运用极限平衡法及有限元强度折减法对碎石土类边坡进行稳定性分析,确定边坡的潜在滑动面;运用反分析计算边坡达到所要求的安全系数时需要的主动支护力,根据计算结果对边坡进行加固设计。
The stability of a debris slope is analyzed and the slide surface is defined by limit equilibrium method and strength reduction finite element method. The desired active support force is calculated to meet the requirement of safety factor of slope by back analysis. According the computed results above, the slope is to be conducted with strengthened design.
