| 中文摘要: |
| 本文在国内学者对大寨崩滑碎屑流成因机理和运动特征研究的基础上，通过大寨崩滑碎屑流的地质环境背景、堆积体分布特征分析，对其运动特征和成因机理进行了探讨。研究认为：地下水水头对崩滑体失稳破坏起着主要作用，变形破坏过程为岩体松弛—软化—动水压力—崩滑，碎屑流表现为能量转化和冲击液化，运动过程可划为“启动加速—惯性力作用减速—加速—减速停滞”四个阶段。 |
| 英文摘要: |
| On the basis of the domestic study of Dazai slump debris flood motion feature and genesis mechanism，by analysis the geo-environmental background and accumulation distribution features，its motion feature and genesis mechanism are discussedIt’s thought the groundwater head is the main reason which cause the slump body unstable，the process is relaxation-softening-hydrodynamic pressure-slump，the debris flood assumes energy conversion and shork liquefaction，the motion process can be divided into 4 phases: start and speed up-speed down by inertial force-speed up-speed up and stand still |
