| 摘 要： | 详细介绍了三峡库区马家屋场-后坪滑坡体的特征，收集了大量软弱结构面资料，研究了各软弱结构面的组合关系，运用优势面理论，合理解释了该滑坡体的成因。采用剩余推力法，对滑坡体在各种不同工况下的稳定性作了科学分析，并对滑坡体在三蛱水库蓄水以后的稳定性作了合理预测，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。 |
| 关 键 词： | 滑坡 成因 稳定性 优势面理论 工况 三峡库区 |

| Abstract: | The Majiawuchang-Houping landslide lies in Wushan county in the region of the Three Gorge dam area.The main part of new Shuanglong town is on the landslide.The characteristic of the landslide was introduced in detail.A great deal of data about weak structural plane were analyzed,the combinatorial connection of various weak structural planes were studied,and preferred plane theory was used to explain the origin of the landslide.Remained Thrust Method was used to study the stability of the landslide in diverse engineering case.Meanwhile,the stability of the landslide was forecasted after Three Gorge dam area would be inundated.The study indicated that,the landslide was steady at present,and the water of Three Gorge dam area has prodigious influence on the landslide,the landslide would lost its stability after Three Gorge dam area was inundated. |
| Keywords: | landslide reason stability preferred plane theory engineering case Three Gorge dam area |
