摘要
本文以张门扎沟泥石流为例,介绍了其形成条件,分析了其基本特征、形成机制,认为沟内泥石流固体物源丰富,具有良好的泥石流发育条件,具有较强的危险性。提出“缝隙坝+拦砂坝+排导槽+桥涵(场镇内)+盖板涵(8#支沟)+沟道整理及清淤”的防治方案,为同类型的泥石流防治工作提供借鉴与参考。
Taking the debris flow of Zhangmenzhagou as an example,this paper introduces its formation conditions,analyzes its basic characteristics and formation mechanism.It is concluded that the debris flow in the gully is enriched in solid material sources,has a good condition for debris flow development and has a strong risk.The prevention and control plan of"gap dam+sand dam+drainage channel+bridge and culvert(in the field town)+cover culvert(8#branch trench)+gully finishing and dredging"is proposed,which provides reference for the prevention and control work of the same type of debris flow.
