| 摘 要： | 藏曲口滑坡位于藏曲与金沙江交界处的金沙江右岸波罗水电站下坝址上游。藏曲口滑坡是金沙江上游典型的滑坡，研究该滑坡的成因对金沙江上游的滑坡研究具有极大的意义。稳定性研究是对坝址的选取的必要条件。本文从滑坡体基本条件分析入手，分析滑坡的成因机制，计算了滑坡体稳定性，准确、合理地分析评价藏曲口滑坡稳定性，为滑坡坝址的选取提供了理论基础和地质依据。

| Abstract: | Zangqukou landslide is, nearby the up dam site of the Boluo hydropower station,on the right bank of Jinsha River, which is not far from the accordant junction of Jinsha River and Zangqu. If the landslide is not stable, it will move into the river, and huge waves will take place, as a result the dam may be destroyed. In this paper, the author analyses the basic conditions of the landslide at first, and then researches its formation mechnism and calculates the stability of it, and at last estimates the stability condition of the landslide accurately and reasonably. Accordingly, theoretical elements and geological foundations for improving slope stability are given. |
