| 摘 要： | 受三峡水库蓄水影响,二道河滑坡出现了变形加剧现象。通过监测数据分析和蓄水过程中滑坡渗流及稳定性数值模拟,分析了滑坡的变形演化过程及变形机制。结果表明:二道河滑坡从开始变形到三峡水库不同阶段蓄水的过程中,经历了由推移式转化为牵引式、由悬浮减重型转化为动水压力滞后型的过程,滑坡变形的地质力学模式为蠕滑—拉裂型。对滑坡变形机制转化的分析可供类似滑坡的分析研究参考。

| Abstract: | Due to the impact of the Three Gorges Reservoir, the Erdaohe landslide occurred deformation intensified phenomenon. In this paper, combined years of monitoring data with the numerical simulation of Seepage and stability of the landslide under the process of stage water storage to analyse the deformation evolution and deformation Mechanism of landslide. The results show that: from the initial deformation of the landslide to the process of stage water storage, deformation Mechanism of erdaohe landslide is from plusus mode to d tractive mode,from float effect weight reduction mode to penetration retarded mode, the geological mechanics model of the landslide is creep-cracking. The research of transformation of deformation Mechanism of landslide can provide reference for the analysis of similar landslide. |
