| 摘 要： | 为了完善土钉支护边坡稳定的极限分析设计方法,对土钉支护边坡稳定的极限分析计算方法进行研究.基于塑性极限分析上限定理,结合传统条分方法,建立了土钉支护边坡稳定性安全系数计算式.同时,采用该计算式与规范法分别探讨了重度、粘聚力、内摩擦角、土钉抗拔力以及土钉层数对边坡稳定性的影响.分析结果初步表明:本文公式与现行规范法分别构成了土钉支护边坡安全系数的上下限,可为综合评判土钉支护边坡的稳定性设计提供参考.

| Abstract: | In order to perfect the limit analysis design method of soil-nailed slope,limit analysis on stability calculation of soil-nailed slope was researched.Based on limit analysis plasticity theory and traditional slice method,a formula to calculate the safety factor in stability of soil-nailed slope was built.Then this formula and the Chinese specification method of soil-nailed slope were used separately to discuss the stability influence of the factors such as unit weight,cohesion,internal friction angle,anti-p... |
