绵竹市清平乡塌洞沟泥石流发育特征及成因机制分析

Characteristics of Collapse Debris Flow Development in Qingping Village in Mianzhu City and Genetic Mechanisms Analysis

清平乡塌洞沟受"5·12"地震影响,沟域内产生了大量松散物源,在暴雨等诱发条件下已爆发多次泥石流灾害。通过对该泥石流沟的详细调查,将沟域分为形成流通区及堆积区,并研究各区段冲淤特征及该泥石流的堆积特征,并对其成因机制进行分析。

Affected by the 5·12 earthquake, the Tadonggou ditch domain generated a lot of loose material source, which has erupted repeatedly debris flows in heavy rain and other predisposing conditions. Through a detailed investigation of the debris flow, we divided the ditch domain into formation circulation area and stacking area, and study the alluvial deposition characteristics and accumulation characteristics of each section. We also analyzed the formation mechanism of the debris flow.
