| 摘 要： | 以某公路经过花岗岩开采区危岩边坡为研究对象，分析危岩段的边坡特征，对危岩体特征进行了分类，运用RocFall软件模拟滚石崩落轨迹，综合预测了滚石冲击能量。研究表明:C片区滚石风险最高，部分危岩对公路冲击能量可以达到20 070 kJ，冲击速度高达47.38 m/s；建议加强该路段的被动防护网设计。

Analysis on Motion Locus and Impact Energy of Collapsing Rock in High and Steep Slope |
| |
| Abstract: | Taking the risk rock slope of a highway passing through granite mining area as the research object, the slope characteristics of the rock section has been analyzed, the rock characteristics has been classified, the rockfall trajectory has been simulated by RocFall software, and the impact energy of the rock has been comprehensively predicted.The results show that the risk of rockfall is the highest in Zone C. The impact energy of some dangerous rocks on the road can reach 20,070 kJ, and the impact speed is up to 47.38 m/s. It is suggested to strengthen the design of passive protection net in this highway section. |
