摘要
滚石灾害具有在同一地区连续发生的特点,其防护措施的合理设置极其重要。通过rocfall模拟软件,在同一边坡上对不同质量的滚石进行灾害模拟,观察滚石的运动轨迹和其产生的动能和反弹高度,大致预测滚石灾害的影响范围。通过运动轨迹、动能和反弹高度这三个因素来模拟该边坡在什么地方需要设置什么样防护措施,能够很大程度的降低滚石灾害所带来的损失。
Rock fall could repeatedly occur at the same location so that the installation of preventive measures at appropriate areas are very important.The research on the rock fall mechanism requires the accurately simulation of the trajectory of the falling rock for the minimization of the potential rock fall hazard.The falling rock trajectories with different weights on the same slope are simulated by the ROCFALL software.The limits of the rock fall hazards can be estimated by the observation of the falling rock trajectory,kinematic energy and the rebound height.The preventive devices can also be appropriately installed by on the study.
