Abstract: Bedding rock landslide is a common slope disaster. The disaster strength of landslide is closely related to rock mass structure and terrain. It has important theoretical significance to assess its risk taking into consideration of the structure of the landslide. Firstly, the structural factors to the effect motion of bedding rock landslide are analyzed. The geological structure model of landside is put forward. Then, the basic law of the different structure landslide kinematics parameter is analyzed. The motion process of the different landslides that have different sliding body structures, slope angles and initial velocities is tested by the physical model. Lastly, the risk parameters of different structure bedding landslides is put forward by summarizing the tested data and risk calculation model of landslides. It indicates that:(1)Bedding rock landslide can be divided into three structures, similar granular, layer and block structure. When considering terrain, rock mass structure, slip surface, and layer structure can be divided into three subcategory in further; (2)Seven types of landslide structures are simulated by physical model test. The results manifest the following. The values of the terminal velocity of the active slide(vt),the influence range(L1) and impact strength(1) for the layer rock(Ⅱ), the blocky rock(Ⅳ), and the similar granular rock(Ⅶ) are ranked the highest, the second and the third; (3)The values of vt of the multilayer blocky rock with joints(Ⅴ),the multilayer rock(Ⅱ), and the multilayer blocky rock(Ⅳ) are ranked the highest, the second and the third. The rock Ⅳ has the largest of L1. The rock Ⅱ has the largest of 1;(4)The vulnerability strength of slide body for the blocky rock(Ⅳ and Ⅴ),the multilayer rock(Ⅱ and Ⅲ),the similar granular landslide(Ⅶ), and the single layer rock(Ⅰ) are ranked the No.1 to No.4 respectively. The strength indices of the back in accumulation area for(Ⅱ、Ⅲ and Ⅴ),the Ⅳ, Ⅰand Ⅶ are ranked the highest to the lowest, respectively. The strength index values of the front in the accumulation area for Ⅱ, Ⅴ, Ⅳ, Ⅲ and Ⅰ are ranked the highest to the lowest, respectively.
