广汉市红层地区滑坡地质灾害形成机制

Formation Mechanism of Landslide Geological Hazard in Red Bed Area of Guanghan City

通过总结分析广汉市红层地区滑坡地质灾害的易发规律,通过查明滑坡的地形地貌特征、边界特征、变形破坏特征;掌握滑带性质和空间形态,滑体、滑带、滑床的物质结构组成;以及滑坡形成的雨量特征、汇水条件、水力特性。总结出各类滑坡的形成条件及演化过程,深入分析广汉市红层地区各类滑坡的特点及成因机制。

This paper summarizes and analyzes the prone law of landslide geological disasters in red bed area of Guanghan City, and finds out the topographic and geomorphic characteristics, boundary characteristics, deformation and failure characteristics of landslide;Master the nature and spatial form of sliding belt, and the material structure composition of sliding body, sliding belt and sliding bed;And the rainfall characteristics, catchment conditions and hydraulic characteristics of landslide formation. The formation conditions and evolution process of various landslides are summarized,and the characteristics and genetic mechanism of various landslides in the red bed area of Guanghan City are deeply analyzed.
