LONG RUNOUT ROCKFALL-LANDSLIDES AND THEIR FORMING CONDITIONS

  • 摘要: 高速远程崩滑所造成的地质灾害极为严重,波及范围大,早已引起国内外工程技术人员的关注。2008年 5 12 汶川8级地震所诱发的崩塌和滑坡数以万计,其中高速远程崩滑数量虽不多,但是灾害严重。与一般崩塌和滑坡相比,高速远程崩滑的形成条件究竟有何差异?为了预测高速远程崩滑灾害的严重性和波及范围,以便为国土规划和防治对策设计提供依据,作者依据本人的工程实践经验并搜集分析了国内外所发生的高速远程崩滑实例,在前人研究的基础上,总结了高速远程崩滑的特征,系统地分析了影响高速和远程的因素。本文在考虑地震、降雨、地下水、采矿活动等因素作用导致斜坡失稳启动前提下,从崩滑体特征及其所处地质环境出发,提出形成高速远程崩滑必须同时具备以下3个条件:(1)崩滑体规模巨大,体积在106m3以上; (2)剪出口高悬,高差达数十至数百米; (3)存在有利于动体运动的地形条件。这为进一步预测高速远程崩滑的空间分布提供了重要的研究内容。
