摘　　要：针对物源剧增、狭陡沟道、小流域泥石流沟泥石流防治,提出一种具有强力消能作用的梯-潭型泥石流排导槽;介绍了梯-潭型泥石流排导槽的结构特征;分析了梯-潭型泥石流排导槽的排导原理,指出梯-潭槽在震后泥石流治理工程应用中的防止磨蚀和冲刷的优势,为进一步研究泥石流在排导槽中的运动特征,泥石流与梯-潭段的相互作用机制,关键设计参数的确定与优化打下基础,对于提高泥石流防治技术水平及新型排导槽的推广应用具有重要意义。A debris flow drainage channel with step-pool configuration （DCSC）for the small watershed with high gradient and abundant loose mass is proposed.The working principles are analyzed after a detailed introduc-tion of the structure of DCSC.The analyses show that the DCSC has its advantages in abrasion and scouring for the engineering mitigation in the disaster areas.The research findings results could provide reference for the further ex-ploration of DCIS such as the dynamic behavior of the channelized debris flow,the energy loss mechanism of debris flow in step-pool system and parameter determination,which are of great significance to improve the techniques lev-el and enlarge the application range of mitigation engineering.
