| 摘 要： | 研究了三峡库区某滑坡的工程地质条件及滑坡体基本特征的基础上，分析了诱发坡体失稳的主要因素；据岩土样品的试验值、现场大剪值，结合地区经验值及反算值，确定计算滑坡稳定性及剩余滑坡推力的抗剪强度参数，考虑到未来三峡水库蓄水，在不同工况下对滑坡体进行稳定性计算，结果表明滑坡整体在各种条件下是稳定的，次级滑坡体在饱水及水库蓄水后，处于临界蠕滑或失稳状态，需尽快进行治理。

| Abstract: | Based on the study of engineering geology condition and basic properties of landslide in Three Gorges Reservoir area,the main factor inducing slope failure is analyzed.According to the test data of soil sample,the data of site investigation,the parameter of the landslide’s stability and the anti-shearing strength parameters were gotten.Because of water in the reservoir of Three Gorges,the result of the stability of the main landslide and the sub-landslide under the different conditions were caculated.The results show that the main landslide is stable in different conditions while the sub-landslide is in critical creeping motion when the landslide body is in water-saturation.Therefore,this landslide need to be controlled as soon as possible. |
