| 摘 要： | 三峡库区作为地质灾害的多发地区，有关构造特征与滑坡之间的因果关系及相同局部构造上多个滑坡个体之间的因果关系研究很少。在应用断层相关褶皱理论方法的基础上,结合工程地质研究现状，以作辑托背斜和巴东断裂为研究重点，对局部构造与滑坡类型之间的关系进行了深入研究。结果表明：大型滑坡发生与局部构造类型及河流切割局部构造的部位相关，不仅体现于对单个滑坡的控制，更体现在对整体岸坡演化规律、个体滑坡演化因果关系的控制上。对研究区而言，滑坡的形成与作辑托背斜构造样式和巴东断裂的反转活动相关，也与长江切割局部构造位置相联系，使滑坡类型在局部地段发生根本性转变，表现出岸坡破坏发展空间演化过程有很强的方向性。 |

| Abstract: | Geological disaster occurs frequently in the three gorges reservoir area, but there is little research on causal relationships between landslide and structural characteristics. And the relative relation of a number of individual landslides in the same local structure has been studied rarely by scholars. Based on the application of fault related folds theory, combined with the engineering geology researches, regarded Zuojituo anticline and Badong fault as the focal point of study, in this article the relation between local structure and landslide type is studied. It shows that the cause of large-scale landslide is related with local structure type and local structure parts where are subjected to cut by rivers, which control causal relationship between the evolution rule of individual landslide and the whole bank slope by a deeper level, but not only reflected the control of a single landslide. In working area landslide formation is related to Zuojituo anticline style and Badong reverse structure, and also related to the river cutting local structure part. Therefor the landslides change fundamentally in local part, and have a serious directivity during evolution of bank slope damaging in space. |
