ABSTRACT
Rock-falling slope disaster is a common geological disaster in mountainous areas of China, which is characterized by wide distribution, concealment and suddenness, etc. It is difficult to implement all-round treatment, and once the disaster occurs, it will cause serious loss of life and property. At present, the three main problems of slope rolling stone disaster are this: 1. Study on the characteristics of rolling stone movement, including the trajectory, impact force and protective measures of rolling stone. 2. Monitoring and early warning of slope rolling stone disaster, summarizing the commonly used monitoring methods and instruments, and pointing out the development direction of slope rolling stone monitoring in the future; 3. Combing common protection technologies of slope rolling stone disaster. On the basis of summarizing the above research problems, the existing problems and future development trends in the research of rolling stone disaster are pointed out: 1. When using numerical simulation to study the motion characteristics of rolling stones, the factors such as the crushing of rolling stones, the shape of rolling stones and the shape of the earth's surface should be considered, so as to better fit the actual motion situation of rolling stones and make the simulation results more accurate; 2. In the monitoring and early warning of slope rolling stone disaster. We should pay attention to the research on the separation stage of the rock-rolling disaster on the slope, and consider the index system based on the combination of dynamic index and static index to judge the risk degree of the rock-rolling disaster on the slope.
