针对火山泥石流实验研究的空缺，基于对长白山火山泥石流的研究，研制了一种火山泥石流室内物理模拟实验装置。与国内外同类实验室相比，实验装置具有变坡幅度大、操作简便的特点。用该装置不仅可以进行实验测试泥石流体积浓度影响因素，还能重现泥石流暴发过程及特征，并以此为基础进行泥石流堆积范围实验。%In view of the vacancy of the experimental study of lahar , a physical simulation experiment device was developed for lahar on the basis of the early study on the research for lahar in Changbai Mountain .Compared with similar laboratory at home and abroad , the experimental device has a larger range of slope and can be operated easily .It is easy to find out how the volume sediment concentration changes with different influence factors by using this device .It is also easy to reproduce debris flow process and characteristics of the outbreak .Furthermore , risk range experiment can be carried out with the aid of this device .
