摘　　要：首先论述了四种沙石体运动模式,还通过理论推导,求解沙石体运动的加速度、末速度和平均速度的计算公式,最后分析了沙石体在多级变坡斜面上加速运动的速度计算方法。The loose debris flow in saturation or supersaturation due to rainstorm, meltwater of ice and snow and groundwater etc. occur landslide under gravity action, and then, all of them may form debris flow. Four motion patterns after debris body initinting are systematically discussed in this paper. The calculating formulae of motion acceleration, final and mean velocities of debris bodies in various conditions are derived. At last, the calculating method for accelerated motion of debris bodies on the slope surfaces in analysed.
