Research on Prevention Parameters and Prevention Measures of Dangerous Rock Mass in High and Steep Slopes
Accurate identification of dangerous rock masses and effective restoration of their actual rolling conditions during collapse are crucial difficulties in preventing and controlling collapse disasters.Taking the dangerous rock masses in Shanyi Village,Kunming City as an example,this paper employed field investigations,unmanned aerial vehicle(UAV)three-dimensional(3D)oblique photogrammetry and 3D laser scanning technology to extract data from the high and steep slope dangerous rock masses.The RAMMS ROCKFALL software was then used to simulate the movement of the rolling dangerous rock masses,enabling the acquisition of their kinematic paths and parameters during the rolling process.The research results show that a combination of advanced methods,including field investigations,UAV 3D oblique photogrammetry and 3D laser scanning technology,can provide accurate and comprehensive identification and analysis of dangerous rock masses.Furthermore,the RAMMS ROCKFALL software can be utilized for simulation analysis to realistically reflect the movement of rolling dangerous rock masses,allowing for the acquisition of kinematic parameters such as the rolling path,velocity and impact on underlying structures.This information can serve as a valuable reference for the layout and design calculations of prevention and control projects.
