摘要
天梯峡谷内岩石节理裂隙极为发育,岩块破碎,多处形成松动岩块,两侧岩壁陡立,形成大面积危岩带。峡谷内空间狭小,地形复杂,谷底纵坡降达25°,景区道路自峡谷谷底经过,危岩带对过往游人构成极大威胁,经多方案比选分析,最终选择了被动柔性网防治方案。
The joints and fissures of the rock cliffs are very well development and rock crushing in the canyon of heaven＇s ladder,formed loose rockmass at the multi-positions,the cliffs on both sides are steep,formed widespread dangerous rockbelt. Not only the space is narrow,but also the complex terrain in the canyon,the longitudinal grade of the canyon＇s bottom is upto 25°,The scenic road go through by the canyon＇s bottom,The dangerous rockbelt will be pose a great threat to past visitors,Through comparison analysis of various schemes,finally,the treatment method of the flexible passive network be chosen.
