Design and application of multifunctional physical model test device for movement and accumulation process of rapid long-runout landslide

There are many factors affecting the movement and accumulation process of rapid long-runout landslide. During the developing the physical model test device, it is necessary to meet the needs of multi-factors, so as to achieve multi-functional purposes. The device is 3.40 m long, 0.56 m wide and 1.35 m high in initial state (vertical angle=20° and horizontal angle=0°). The design includes three modules: volume adjustment of slide body, slope adjustment of upper slide groove and horizontal angle adjustment of horizontal slide groove. Two kinds of materials, 3 mm thick stainless steel plate and 8 mm thick tempered glass, are used as the processing raw materials, leading to good durability. Moreover, the universal wheel is installed in the form of component assembly to facilitate the handling of the experimental instrument. Based on sand and pebble granular materials, the physical model tests with respect to the movement and accumulation process of rapid long-runout landslide are preliminarily carried out by using the developed device. The effects of slope, horizontal angle, height of sliding body and base material on sliding distance are briefly analyzed.
