椿芽树沟潜在泥石流动力学特征及防治工程探讨

Dynamic Characteristics and Control Engineering of Chunyashu Potential Debris Flow

"5.12"地震形成的崩塌和滑坡为椿芽树沟泥石流的暴发提供了物源条件,需要对有潜在危险的泥石流进行治理。结合相关文献和野外勘察数据,分析计算了该泥石流的特征参数,并在此基础上提出了2种治理方案,通过技术经济比较选定"拦挡坝+单边防护堤+排导槽"的治理方案。该研究结果为椿芽树沟泥石流的防治提供了可靠的依据。

The landslides and collapses caused by"5.12"earthquake provide material source conditions for the outbreak of debris flow in Chunyashu gully,and it is necessary to control the potentially dangerous debris flow.Combined with the relevant literature and field survey data,the characteristic parameters of the debris flow are analyzed and calculated,and on this basis,two control schemes are proposed.Through the technical and economic comparison,the control scheme of"retaining dam+unilateral protective dike+drainage channel"is selected.The research results provide a reliable basis for the prevention and control of debris flow in chunyashu gully.
