汶川地震作用下滴水岩滑坡分析

Analysis on Dripping Rock Landslide under Action of Wenchuan Earthquake

以滴水岩滑坡为例,对其环境地质条件、类型、性质,滑坡形成机制,以及在汶川大地震作用下滴水岩滑坡复活变形的机理进行分析。地震对滑坡的影响主要是使滑坡体内部发生局部的不利重新组合。为整治滑坡提出了综合措施,保证了工程安全。基于地震与滑坡关系的复杂性,建议针对铁路等国家基础设施酌情提高抗震设防等级。

Taking dripping rock landslide as an example, the environmental and geological conditions, type, properties, genesis mechanism, and its revival and deformation mechanism under the action of Wenchuan Earthquake were analyzed. What effect of the earthquake on the landslide mainly includes the local disadvantage for recombination arose inside the landslide. Then the comprehensive measures for the landslide control were proposed to ensure the safety. On the basis of complex relation between earthquake and landslide, it is suggested that the earthquake protection grade of national infrostructure, such as railway, should be increased where appropriate.
