| 摘 要： | 滑坡型泥石流是一种特殊的能量转换体运动类型。它是在很短时间内，由滑坡体的位能快速转化为动能的一次性滑动——流动堆积。滑坡型泥石流的活动是由块体在整个连续运动过程中发展的两个阶段(先滑坡，后泥石流)组成。滑坡型泥石流与一般的滑坡、泥石流不同，它兼具滑坡和泥石流的一些特征。滑坡型泥石流速度快，冲击力强，破坏性大。在理论上和国民经济影响方面有独特的研究意义。

| Abstract: | The landslide type debris flow is a special motion type of energy conversion body and represents a sudden sliding flowing deposition due to quick conversion of potential energy of a landslide body into violent kinetic energy.It consists of two stages developed in the process of continuous mass movement,deffevs from the general landslide and debris flow,and hence,has the features of the both landslide and debris flow.It is characterized by high velocity,strong striking force and severe destruction.It is of significance to study this kind of debris flow in theoretical and practical aspect. |
