【摘要】 针对滑坡所处的地质环境条件,运用地质调查、现场钻探、变形破坏监测、稳定性评价的方法和手段,结合水库运行、迁建城镇建设和开采砂金等人类工程经济活动,对金洞滑坡的急剧复活变形进行了成因机制研究。结果表明,金洞滑坡的复活是在老滑坡堆积体的基础上,因水库水位消落直接引起的变形破坏。人为开采砂金形成地下采掘坑道以及城镇场地不合理开挖和堆填活动进一步加剧了其破坏程度。这一事例对大型水电站建设中移民集镇的选址和前期论证工作有借鉴意义。
【Abstract】 Based on the investigation of the engineering geological environment,with the geological investigation,field drilling,deformation and failure monitoring,stability estimation,the mechanism of abruptly revived deformation is researched.The relationship of the landslide revival mechanism with the human engineering activity,including mining gold,unreasonable seclection of construction sites for city and town buildings,ascending and descending of the reservoir water are discussed.In addition,the attention to the reservoir construction should be more emphasized.
【Key words】 Jindong landslide; revival deformation; old landslide accumulation; rise and drop of water level; human activity;
