摘要
滑坡是三峡工程库区主要发生的地质灾害 ,四川巫山县四道沟滑坡的研究及防治工作是关系到巫山新县城地基是否稳定的最重要的因素之一。通过平面弹塑性有限元法及SARMA法以自重 +静水压力、自重 +静水压力 +动水压力、自重 +静水压力 +动水压力 +地震力等6种方案进行稳定性的计算分析 ,从充水前后不同标高滑体的塑性分布状态分别讨论巫山县四道沟滑坡的变形破坏机理及其稳定性 。
Slope is major geologic hazard in the Three Gorges area. Sidaogou slope is one of the most important slope relevant to stability of the new Wushan County. In this paper, finite element and SARMA methods are applied to analyze the slope stability, similarly, the theory of deformation destruction and the condition of stability are discussed in different conditions. Therefore, there is a basement for the slope monitoring and treatment.
