"5·12"汶川大地震诱发了大规模以滑坡、崩塌为主的地质灾害,这些震害地区改变了原有的地貌形态,形成多处堰塞湖,毁坏民房和道路,使之成为严重的次生滑坡灾害危险区域.以成都市的都江堰市、彭州市、崇州市、邛崃市、大邑县地震区为研究区,分析了滑坡分布与震区地质地貌条件和宏观烈度的统计关系.在确定宏观震中位置的基础上,采用最大地震滑坡震中距方法研究了不同规模滑坡的分布特点,并得到了线性分布的规律.

The earthquake of May 12 in Wenchuan induced lots of landslides ,rockfall and topographic alteration, which formed many barrier lakes, destroyed houses and roads and led to a dangerous zonie of secondary landslide disasters . In this paper,taking Dujiangyan,Pengzhou,Chongzhou,Qionglai and Dayi in Chengdu City as research areas,the statistical relationship of laudslide distribution with geological /geomorphological condition and macroscopic intensity was analyzed . Based on the determination of macroscopic epicentral location, the distributive characteristics of landslides with different scale were researched by using maximum epicenter distance method and a linear distribution rule are obtained.
