摘　　要：结合跨过沟野外调查及地质背景等资料,论述了跨过沟泥石流的流域特征、发生条件以及动力学特征,通过定性和定量两种方法对跨过沟泥石流进行了危险性评价,得出如下结论:跨过沟泥石流为暴雨沟谷型泥石流,正处于发展期,表现为中度易发、中度危险,在强降雨影响下暴发泥石流的可能性较大。Based on the field investigation and geological background in Kuaguogou,the paper discussed the basin characteristics,occurrence conditions and dynamics characters of Kuaguogou debris flow. By using quantitative and qualitative evaluation methods the risk assessment of Kuaguogou debris flow was evaluated. The conclusions are as follows,the Kuaguogou debris flow is a strong rainfall gully type and under development stage,which has a high risk under heavy rainfall.
