Rockfall Risk Evaluation System with Laser and Drone Measurement

摘要

Railway Technical Research Institute (RTRI) developed a system used for detecting rock blocks unstably located on a rock slope by conducting noncontact measurement at a remote location. By measuring the vibrations and geometries of rocks located at a distance or at a high altitude through laser measurement and aerial survey through the use of a drone, and by using the rock model s FEM analysis results and the measured rock vibration characteristics based on the aerial survey data, we would like to propose a method for evaluating the risk of rockfall at ordinary times and when an earthquake occurs, and establish a series of feasible procedures as a rockfall risk evaluation system.
