| 摘 要： | 针对湖北省三峡库区秭归县头道河Ⅱ号滑坡现状条件下的明显变形迹象，本文对该滑坡进行了综合的分析和研究，详细介绍了该滑坡的地质背景及滑坡特征。采用剩余推理法，对滑坡体在各种不同工况下的稳定性作了科学分析，并对滑坡体在三峡水库蓄水以后的稳定性作了合理评价。结果表明，滑坡体在目前状态下基本稳定，三峡水库蓄水以后，将对滑坡体稳定性产生较大影响，极有可能导致滑坡体失稳，据此结合工程实际提出了一些可行的防治措施及建议。

| Abstract: | The present paper discussed deformation and displacement of the No. 2 landslide at Toudaohe of Zigui County in the Three-Gorges Reservoir region, Hubei Province, and introduced geological background and characteristics of this landsides in detail. A remainder theorem method was used to study the stability of the landslide in diverse engineering cases. Moreover, the stability of the landslide after impounding of the Three-Gorge Reservoir was evaluated. The study indicated that the landslide was steady at the present state, but the impounding of the Three-Gorge Reservoir will obviously a influence the landslide, causing the landslide to lost its stability. According to the calculated results, some possible countermeasures and recommendations were advised in combination of engineering reality. |
