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.

Key words:
landslide;debris flow;landslide-type debris flow
