摘要
针对五峰山斜坡变形破坏的基本特征,运用板裂结构理论和宏观地质法,分析了斜坡变形的影响因素、破坏机制和稳定状况。认为五峰山斜坡变形是各种作用长期积累的结果,不论有无其它触发因素,在自然状态下斜坡均会发生变形,变形模式为由下坡至上坡发展的溃屈破坏。位于陡坡上的碎块物质,当临界雨强达到7 6mm 10min时,将发生坡面泥石流。该研究对长江沿岸类似条件下斜坡的稳定性评价和治理具有参考价值。
According to the deformation phenomena, the main stability influence factors and deformation mechanism are studied, this slope deformation is riot break, the deformation started from the lower of the slopes. On the condition of intense rainfall more than 76mm per ten minutes, most of lose deposits on Wufeng mountain slopes are unstable and form surface mudflow. This study will provide reference for the similar slopes on the banks of the Three Georges.
