摘要
近十几年来，随着对崩滑灾害的研究深入，伴随高速滑坡的一种新形式的地质灾害－崩滑碎屑流已愈来愈引起工程地质与环境地质界的关注。特别自我国近十几年来典型崩滑碎屑流出现之后，人们发现碎屑流与滑坡在其形成条件、运动形式、流动速度及防治措施等方面都存在着本质的不同。本文在前人资料和研究的基础上，根据野外地质调查和研究，认为碎屑流是一种高速松散固体流，不存在滑移面，并受三个基本条件的控制，即固体物质条件，边界限制条件及潜在聚能条件，在此基础上，对崩滑碎屑流的类型划分进行了系统的讨论。
ith the further study on the high-speed landslide in recent years, a new form of geological hazard -debris flow which is often accompanying with the high-speed landslides hasdrawn more and more attention in the engineering geology field, particularly since the accurencesof Shalashan Maintain Front debris flow, Xintan Sanyogou debris flow and Shijiapou debris flow.It has been discovered that there are some essential differences with land slides in its forming condition, moving form, moving speed and its prevention measures, etc.Based on the systematically geological investigation and study, it has been found that the debris flow is a kind of high-speed loosely-grained sliderock mass and has no sliding planes andthat there exist three basic conditions which control the accurence of debris-flow, that is solidmaterlal condition, boundary restrictive condition and potential sliding energy condition. Finally,it has taken a systematical discussim on the forming types of the Debris flows coused by landslides& Falls.
