弯曲-拉裂型滑坡形成机制和稳定性分析——以木里河卡基娃滑坡为例

The formation mechanism and stability analysis of bend-crack landslide: Taking the Kajiwa landslide of Muli River as an example

卡基娃滑坡是木里河卡基娃水电站拟建坝址下游左岸的特大型基岩古滑坡,是川西高山峡谷区弯曲-拉裂型滑坡的典型代表,本文结合河谷地貌史的研究,分析了滑坡的形成机制,采用宏观分析和定量计算相结合的方法对滑坡稳定性进行了评价,对研究同类型的滑坡有一定的借鉴意义。

The Kajiwa landslide is a large bedrock and ancient landslide which is located in the left bank in downstream of the plan to build the dam site of the Kajiwa hydropower station of the Muli River,and it is the typical representative of the bend-crack landslide in high mountains and canyons in western Sichuan.Based on the study of the history of the river-valley landforms,the formation mechanism of the landslide is elaborated.According to the macro analysis and quantitative calculation method,the stability of landslide is evaluated.Therefore,the results have a certain significance in the study of the same type of landslides.
