摘要
在极限分析理论的基础上,研究三台阶边坡的稳定性问题。基于极限分析上限定理,建立三台阶边坡的破坏机构,推导其外部功率与内部能量耗散功率的平衡方程,求出其临界高度的上限解。将由本文计算出的稳定系数与已有计算结果进行对比,证明该方法的正确性及有效性。
The stability of tri - beaches slope was analyzed on the basis of limit analysis. The failure mechanism of such slope was conducted based on upper bound theorem, and the external work rate and internal energy dissi- pation rate were calculated. The upper bound solution of critical height was obtained. The present results of sta- bility coefficient agree well with previous results, which shows the validity of proposed meth
