卡基娃滑坡的形成机制和稳定性浅析

On Genetic Mechanism and Stability for the Kajiwa Landslide

卡基娃滑坡位于木里河卡基娃水电站拟建坝址下游左岸,为一特大型基岩古滑坡,其稳定性关系到建坝、建库的可行性和安全性。通过勘察,掌握了滑坡的边界条件、变形特征和形成机制;结合河谷地貌史的研究,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,为下一步工作奠定了基础。该滑坡是川西高山峡谷区弯曲-拉裂型滑坡的典型代表,通过其形成机制和稳定性的研究,对今后认识和研究该类型的滑坡有一定帮助。

The Kajiwa Landslide lies on the left bank of the Muli River nearby the planned Kajiwa Hydropower Station, being a giant ancient bedrock landslide. Its stability is of great importance to the hydropower station. This paper deals with its boundary condition, deformation characteristics and genetic mechanism and assesses its stability. This landslide is representative of bend and pull-apart landslides in alpine valley, west Sichuan. Study of the genetic mechanism and stability is of significance to understanding the same landslide type.
