一次奇特的泥石流

A strange debris flow

在连续晴朗且没有大容量地表水的情况下,浙江省庆元县安南乡小源村洋尾坑发生了泥石流,与通常认为的泥石流的发生由暴雨、冰雪融水或库塘溃坝等水源激发大相径庭。通过访问灾害形成及活动过程和全面调查地质环境条件,认为该泥石流是滑坡的一种特殊运动形式,属于比较独特的泥流,并展开了活动机理研究。

After many sunny days and without much surface water,a debris flow happened in Yangweigou.It was so different from those common cases in that debris flow is caused by rainstorm,snow melt water or dam burst.Through visiting the witness for the happening process of the disaster and investigating the geo-environmental conditions,a conclusion was drawn that this debris flow is a special landslide,belonging to mud flow.Thus,research was done on the activity mechanism.
