| 摘 要： | “5.12”汶川地震诱发大面积的山体滑坡,直接威胁人类的生命财产安全,但同时也为研究地震对滑坡的影响提供了宝贵的素材。以四川省理县望月寨滑坡为例,在对地震前后滑坡基本特征深入研究的基础上,采用极限平衡法和有限差分法对地震前后该滑坡的稳定性和应力应变特征进行了计算、模拟和对比分析,分析结果与地震前后滑坡的宏观地质现象均具有较高地吻合度。研究成果为深入分析地震对滑坡影响及防灾减灾提供了可靠依据。

| Abstract: | "5.12" Wenchuan earthquake induced a large number of landslides, which had directly threaded human lives and property safety. But at the same time, it also provided valuable material to study the impact of earthquakes on the landslide. Taking Wangyuezhai landslide instantiated in Li city of Sichuan Province for example, on the basis of exhaustively mastering the basic characteristics of landslide before and after Wenchuan earthquake, stability and stress-strain features were then calculated and analyzed by limiting equilibrium method and finite difference method, which could analyze landslide’s deformation features from the respect of stress-strain. The analytical results are consistent with the macro-geological phenomena before and after the earthquake. These results provide a reliable basis for the future study of the impact of earthquakes on the landslide and geohazard prevention &; geoenvironment protection. |
