地震典型滑坡产生机理及防治方法研究

Study on the Generation Mechanism and Prevention Methods of Typical Landslides during Earthquakes

地震滑坡是地震引发的常见地震灾害,地震作为诱发因素,其产生的地震惯性力和超孔隙水压力是直接因素。根据对滑坡的作用过程,可以分为启动动力效应、变形位移加速效应、累进破坏效应三个过程。根据滑坡发生特点,将地震滑坡分为了五种类型,即整体滑动型、碎裂滑动型、坠落~滑动型、倾倒~滑落型和复合型五类,并详细分析了这五种类型的滑动特点、滑动过程和滑动机制。对于地震滑坡的防治具有重要的理论和工程意义。

Earthquake landslide is a common earthquake disaster caused by earthquake.As an inducing factor,earthquake inertia force and excess pore water pressure are direct factors.According to the action process of landslide,it could be divided into three processes:starting dynamic effect,deformation displacement acceleration effect and progressive failure response.According to the occurrence characteristics of landslides,seismic landslides were divided into five types,namely,integral sliding type,cataclastic sliding type,falling sliding type,dumping sliding type and composite type.The sliding characteristics,sliding process and sliding mechanism of these five types were analyzed in detail.It had important theoretical and engineering significance for the prevention and control of earthquake landslides.
