[0002] Landslides are common natural events in mountainous areas. During their movement, they have huge kinetic energy. In severe cases, they may affect downstream infrastructure (such as roads and houses), causing houses and roads to be flooded, thereby causing siltation and blockage of rivers. For a long time, landslide disasters have posed a serious threat to people's lives and property safety. In order to qualitatively and quantitatively analyze the motion characteristics of soil-rock mixtures in motion, many scholars have adopted model test methods to study the motion characteristics of sliding bodies.

Comparative document CN214669049U discloses a large-scale landslide high-speed sliding liquefaction acceleration test simulation device, and the protected claim is "The utility model discloses a large-scale landslide high-speed sliding liquefaction acceleration test simulation device, comprising: a shear liquefaction section is provided at the bottom of the chute; the shear liquefaction section includes: a support matrix and a simulated liquid; the simulated liquid is immersed in the pores of the support matrix. In this scheme, by providing a shear liquefaction section at the bottom of the chute, when the landslide block slides to the shear liquefaction section, it can squeeze the support matrix under the action of its own weight to precipitate the simulated liquid, thereby realizing the simulated shear liquefaction process, and the scheme is also simple and practical, and has good simulated liquefaction effect. "However, the device ignores the influence of the landslide angle, cannot adjust the angle for multiple times to conduct tests, and does not set a direct structure to record effective test data.
