三峡库区土门子滑坡变形破坏机制分析
摘要:在研究土门子滑坡地质环境和变形特征的基础上,对滑坡的成因机制、变形破坏模式及起动机制进行了分析。结果表明,该滑坡为前缘牵引后缘平推式,现处于整体蠕动变形局部滑移阶段,持续强降雨是诱发其失稳破坏的主导因素.针对滑坡体可能沿多个剪出口发生变形破坏等特征、提出了相应工程防治建议,对指导该类工程的设计和施工具有参考意义。
Abstract:This paper studies on the basement of the characteristics of the geology and deformation of the Tumenzi landslide, then do further research on the genetic mechanism, deformation failure mode as well as starting mechanism. The research result shows as follows: first, the deformation mechanism of the landslide is Translational gliding mode; second, the landslide is in the stage of wholly creep deformation with partly slidingl third, the continually heavy rain is the main factor which may results in its broken. At last, put forward the disposing suggestions according to characters of the landslide, which has important significance in guiding the design and construction of this kind of projects.
