Abstract

Abstract

The rock collapse disaster caused by the dangerous rock mass of slope is a geological disaster with strong sudden occurrence and destructive ability. The key to prevent and control the dangerous rock mass of slope is to delineate the influence range of the dangerous rock mass. In order to accurately assess the influence range of the dangerous rock mass of slope, improve the disaster prevention ability of the dangerous rock mass of slope and reduce the collapse threat, it is urgent to improve the calculation model of the influence range of the dangerous rock mass of slope. Based on the survey results of dangerous rock mass in Guangzhou, the types and slope shape characteristics of common dangerous rock mass in slope are summarized, and the physical and geometric model of the influence range of dangerous rock mass is established. The main factors affecting the collapse movement process, such as slope friction, block collision, bounce, fragmentation, properties of contact surface covering and coefficient of restitution, terrain conditions and earthquake, are comprehensively considered. The calculation model of collapse influence range of linear and curved slope under different slope conditions is established by generalized motion process elements, and the expansion coefficient of collapse influence range under earthquake conditions is obtained according to the influence of earthquake force on the kinetic energy of collapse body. On the basis of previous studies, this model further summarizes the geometric model of slope shape classification and formation, and calculates the calculation model of the maximum influence range of dangerous rock mass under common working conditions and different terrain conditions according to the movement process. After obtaining the slope height, slope and surface characteristics, the influence range of dangerous rock mass can be calculated according to this model. Through the verification and comparison of actual cases, the relative error of calculation results is small, and a certain safety distance can be reserved, which can be used for the evaluation of the influence range of dangerous rock mass in common slope slope, and provide a basis for the prevention and control of dangerous rock mass in slope.
