中文摘要：

高速远程滑坡不仅具有运动机理复杂、危害大、发生突然等特点,而且滑坡在运动中经历了斜坡加速、坡脚碰撞、偏转持速效应、减速堆积的过程。通过室内滑坡模型试验,研究了岩土体类型、偏转角和下垫面对高速远程滑坡运动特征的影响。试验结果表明：滑坡体的运动距离受控于岩土体类型,随着偏转角的增大,滑坡运动距离减小,最大堆积厚度增加,同时偏转角对滑坡体有明显的颗粒筛分现象。下垫面摩擦类型对滑坡运动参数具有明显的作用,影响滑坡体最终的堆积形态。试验结果为深入研究滑坡运动速度、运动距离及堆积形态提供了重要的参考依据。

英文摘要：

Landslide of high speed and long distance is characterized as complex movement mechanism, great threat and ab- rupt occurrence. The landslide undergoes acceleration on slope, collision at the slope toe, deflected speed - retaining effect and accumulation of speed reduction in the movement process. Laboratory model tests are used to investigate the influence of the rock and soil type, turning direction angle, underlying surface on landslide movement. The test results show that the movement dis- tance of the landslide is controlled by the rock and soil type. As turning direction angle increases, the movement distance reduces and the accumulation thickness increases. The turning direction angle has obvious particle sorting effect on the landslide. The un- derlying surface friction type apparently influences the movement parameters, which will eventually affect the accumulation shape. The experiment can provide evidence for further studies on landslide movement velocity, movement distance and accumu- lation shape.
