甲学沟泥石流发育特征及防治建议

Characteristics and Control Suggestion of the Jiaxuegou Debris Flow

甲学沟泥石流属暴雨一沟谷型稀性泥石流,历史上曾多次爆发泥石流,对下游居民和公路造成危害。在对甲学沟实地跟踪调查的基础上,将泥石流沟划分为形成区、形成流通区、堆积区三个分区。研究该泥石流沟的地质环境条件及发育特征,查明泥石流的成因机制,有针对性的提出防治措施,对类似地质灾害的评价及治理具有一定的借鉴意义。

The Jiaxuegou debris flow is a non-viscous rainstorm-gully type debris flow which has occurred several times,causing harm to the downstream residents and the highway.This paper divides the debris flow gully into three zones,namely,the formation zone,the circulation zone and the accumulation zone,has a discussion on geological condition,developmental characteristics and genetic mechanism of the debris flow and puts forward some control measures.
