| 摘 要： | 某库岸为典型高山峡谷地貌，斜坡在卸荷作用和重力作用下弯曲拉裂，形成规模巨大的滑坡。水库蓄水后，滑坡可能产生复活，将造成“二道坝”，危及大坝及其它枢纽建筑的安全。结合滑坡区的环境地质条件，滑坡的地质结构特征，分析其形成机制，并在此基础上建立地质 力学模型，再现滑坡形成过程。最后采用定量计算、数值模拟法计算滑坡安全系数、应力分布状态等，对滑坡蓄水条件下的变形及稳定性进行研究和预测，从而为滑坡治理工程设计提供依据。

| Abstract: | As the geomorphology of the studied reservoir bank presents typical mountainous and canyon characteristics,bending and ripping deformation of its slope occurs due to unloading and gravity,thus give rise to large scale landslide.The landslide may reactivate after impoundment of the reservior,hence may endanger the safety of the dam and other structures.Based on the environmental geological condition and the geological structure characteristics of the landslide,a geomechanics model has been established to sim... |
