摘　　要：对江津四面山红岩山危岩进行稳定性验算,计算结果表明红岩山危岩存在进一步发生崩塌的可能性.危岩治理十分必要.对此,提出了该地区危岩灾害防治措施,建议综合采用主被动联合方法进行危岩防治工作.用运动学方法进行落石冲击力检算、腾越计算及弹跳计算,以此结果再结合观测落石的运动轨迹和弹跳高度,以确定拦截防治工程结构物的设计尺寸和材料强度参数.In order to see into stability of unstable rock of HongYan mountain, the calculation model for unstable falling rock has been proposed,whlch based on limit equilibrium theory and rock mass structure theory. To some representative unstable rocks, calculated results showed obvious trend of further collapse, which make it very urgent to deal with this potential hazard. Some synthetic disposing methodes are recommended for controlling unstable rock disasters. Based on falling rock impact force and jumping over height calculations, strength of the SNS and dams for rock hold-up engineering amount were computed.

关 键 词：崩塌落石 稳定性计算 落石运动轨迹 治理原则
