| 摘 要： | 汶川地震诱发了很多地震泥石流.通过对四川省都江堰市虹口乡小沟泥石流沟实地考察和室内实验数据分析,得出小沟泥石流暴发的主要原因是:(1)2008年5月12日汶川大地震导致大量山体滑坡,在四川省都江堰虹口乡小沟流域内大量滑坡体失去了原有稳定性但还没有滑动,(2)强降雨作用使滑坡体运动至沟道内,阻塞束窄沟道,后在洪水冲刷下溃...

| Abstract: | A number of earthquake debris flows were caused by the Wenchuan earthquake.This paper discusses the characteristics and happening conditions of the typical sequential debris flows in the earthquake area.Through field observation of the Xiaogou gully basin located in Hongkou,Dujiangyan,Sichuan Province and laboratory experimental data analysis,it reaches the conclusion that first,many landslides were triggered by the Wenchuan earthquake on May 12,2008 and many potential landslides lost their balance in the e... |
