Deformation characteristics and reactivation mechanism of Hongyanzi landslide in Pubugou reservoir area of the Dadu River

More Information
  • 库水涨落常诱发库岸滑坡变形破坏。为了研究库岸滑坡的变形特征及变形机理,以大渡河瀑布沟水电站红岩子滑坡为对象,通过详细的地表宏观变形调查和对监测数据的深入分析,结合GeoStudio数值模拟,深入研究了该滑坡的变形特征、渗流场、稳定性及库水对滑坡的作用机理。结果表明:红岩子滑坡地表宏观变形显著,累计位移曲线呈“阶跃”式特征,库水下降是滑坡变形的主要诱发因素;库水位由850 m高水位集中下降至830 m以下时,位移阶跃启动,“阶跃”段的累计变形量占全年总变形量的90%以上,当库水位下降速率大于0.5 m/d时,滑坡加速变形;滑坡变形模式为蠕滑-拉裂,库水升降导致滑体内部渗透力的变化,对滑坡稳定性影响很大,引发滑坡“阶跃”变形。
