| 摘 要： | 2010年8月13日在强降雨的作用下,四川省都江堰市龙池镇碱坪沟沟床启动并带动沟道两侧固体物质运动,形成大规模泥石流,冲毁沟口农家乐、龙池公路及沟口一处居民供水设施。碱坪沟泥石流是典型的震区沟谷型泥石流,通过分析泥石流的形成机理及容重、流速、流量、冲出量等动力学参数,得出泥石流的危险范围和威胁对象,并根据沟道中大量崩滑体等各类物源的堆积情况,在降雨作用下对其再次暴发泥石流的可能性进行了分析预测,还根据沟口现场堆积情况提出了防治建议。

| Abstract: | After the bed was activated,the solid material on both sides of Jianping Gully was driven,forming a large-scale debris flow in Longchi Township of Dujiangyan City in Sichuan on August 13,2010,under the action of heavy rain.The debris flow washed away farm tourism facilities,Longchi highway and drinking water supply facilities at the mouth of gully.This is a typical gully-type debris in the earthquake-stricken region.Through analysis on the forming mechanism and dynamic parameters of volume weight,velocity,d... |
