| 摘 要： | 对发育多个规则软弱夹层的岩体边坡稳定性评价方法进行了探讨。在塑性极限分析的基础上，采用机动位移法，提出可以用能量系数作为稳定性评价的标准，并推导了相应公式。通过川藏公路上一个典型滑坡实例的稳定性分析，与极限平衡法进行了对比，证明了本方法的可行性。

| Abstract: | The stability evaluation of a rock mass slope with regular weak intercalated layers is discussed. On the basis of the plasticity limit analysis, the energy coefficient is proposed to evaluate the stability of rock mass slopes using the movable mechanism method, with a set of formula derived. The stability of an actual landslide located at the Sichuan Tibet highway is analyzed using the method proposed in this paper and the traditional limit equilibrium method, respectively. By comparing the results, the evaluation method suggested proves feasible. |
