摘要
边坡滚石是在山区基本建设中常遇到的一种工程灾害 ,其防护结构的设计依据主要是边坡滚石的运动轨迹 ,因而要对这种灾害进行防治 ,首先要确定滚石的运动轨迹。分析了几种主要形式的边坡滚石运动 ,考虑控制滚石运动的主要影响因素 ,从工程的角度建立了一套计算边坡滚石运动轨迹的计算公式 ,并对影响滚石运动的碰撞恢复系数。
Rockfall is a frequent engineering disaster confronted by constructions in mountain areas. The design of preventive structure is based on the evaluation of the rockfall trajectory. So it is very important to properly caculate the rockfall trajectory. The paper has analysed four main types of the rockfall trajectory, picked out the major controlling factors of the trajectory and set up a series of caculation formulas on the view of the engineering utilities. Besides,the paper also studied the impact restitution coefficients and the rolling friction coefficients.
