湘东地区中型中层滑坡成因机制分析和稳定性评价——以双泉滑坡为例

Analysis on the Genetic Mechanism and Stability Evaluation of Medium-sized Middle-level landslide——Take Shuangquan landslide as an example

湘乡市双泉滑坡为湘东地区少见的中型中层滑坡,变形特征明显,严重威胁区内居民的生命财产安全。本文以其为对象,基于野外详细勘查结合滑坡特征对其成因机制和破坏模式进行了深入研究,采用毕肖普法对滑坡的稳定性作出定量评价和预测,提出了综合治理方案,为湘东地区类似地质条件下的中型中层滑坡的防治提供借鉴。

The Shuangquan landslide of Xiangxiang was a rare mid-sized and mid-level one in the east district of Hunan,with obvious deformation characteristics,which seriously threatened the residents’lives and estates there.In this paper,based on the detailed field investigation and landslide characteristics,the genetic mechanism and failure style of the landslide were deeply studied,the stability of the landslide was evaluated quantitatively and predicted by bishop method,and a comprehensive control measures was put forward,which can be used for reference for the prevention and control of the mid-sized and mid-level landslides under similar geological conditions in the east district of Hunan.
