杭州某高边坡危岩体影响范围分析

Analysis on Influence Scope of Dangerous Rock mass on High Slope in Hangzhou

以杭州市"龙山石壁"风貌保护治理工程高边坡为实例,对危岩体的影响范围进行了比较系统的分析研究。通过现场滚石试验,对危岩体影响范围进行了划定,运用Rocfall软件对落石运动轨迹进行了分析,评估其崩落后的滚动距离、危岩体坠落以后可能的弹跳高度,最终得出危岩体的影响范围。

Taking the high slope in the project of ＂Longshan Cliff＂ environment protection as an example,the influence scope of the dangerous rock mass thereon was studied systematically.Through on-site rolling stone test,the influence scope was delimited,and the motion trajectory of rockfall was analyzed with the Rockfall software,by which the rolling distance after avalanche and the possible jumping height of the falling rock were evaluated and,finally,the influence scope of the dangerous rock mass was obtained.
