中文摘要本文在野外调查、室内试验的基础上,对滑坡泥石流化进行比较系统的研究;确定了滑坡泥石流化现象在滑坡流态现象中的地位;并对滑坡泥石流化现象的运动特征进行了分析,在相似模拟中以几何相似控制材料相似得到了比较满意的效果。
英文摘要There are many Landslides which can change into debris flows and caused some great catastrophies. This paper collects the information of the Landslides which occured in recent years in China and studies the Land slides mechanism, movement and model experiment.
With 11 examples of Landslide—deris flow (dry), Landslide --debris flow (mudflow), four curves which show the relationship between volume and sliding distance of every kind of landslides are gotten basing on the curves, the curve of Landslide--debris flow (mudflow) is between the curves Landslide-- debris flow (dry) and Landslide--debris flow on marine bottom.
In the analysis of mechanism, a typical loess landslide is used. The landslide was changed into mudflow in 1981 in China. There are three ways for the transformation of landslide into mudflow which are divided. These stages sre sliding stage, flowing stage and despoiting stage. Besides those, the formulae of volecity, and movement time are obtained. Finaly, a model experiment is taken and got the result of experiment concides with the proctical landslide.
