汶川县泥石流沟在汶川“5.12”地震后的活动趋势
|
摘要
2008年5月12日,四川省汶川县发生了8级强烈地震。震后,灾区内多处暴发了泥石流。以地震灾区汶川县泥石流为研究对象,综合考察了6条处在不同地震烈度和具有不同泥石流形成特点的泥石流沟,分析了泥石流的活动趋势,并探讨了泥石流活动受地震影响的时间规律,为地震灾区的泥石流减灾和防治工作提供参考。
A strong Wenchuan earthquake happened on May 12,2008.Many debris flows were triggered in earthquake stricken area by Wenchuan earthquake.In this paper,we focus attention on the debris flows in Wenchuan County,Sichuan Province.The debris flow gullies in different earthquake intensity areas and with different characteristics were investigated.The activity tendency of debris flows was obtained by analyzing the solid source features of debris flows,such as the volume and location of sediment provided by landslides and avalanche.The time of earthquake effect on triggering debris flow was discussed.These works will provide some references to the prevention and mitigation of debris flow hazard in earthquake stricken areas.
