摘要
金安桥水电站枢纽区左岸边坡为顺向坡，发育缓倾坡外的t1c、t2等泥化凝灰岩夹层及流层面。边坡中分布有B1、B2及B20三个规模较大的崩塌堆积体。左岸边坡的稳定对电站枢纽工程存在较大影响，是金安桥水电站建设面临的重大工程地质问题之一，因此，对左岸边坡的稳定性进行专门的研究具有十分重要的意义。
The left bank slope in the hinge area of Jin＇anqiao Hydropower Station is dip slope, and develops the t1c, t2 and other slugging tuff interlayer and flow layer. The slope is distributed with B1, B2 and B20 three falling accumulation body with relatively large scale. The stability of the left bank exerts great influence on the hydropower station hinge project, which is one of the key project geological issues faced by Jin＇anqiao Hydropower Station. Therefore, it is quite significant for the special study on the stability of the left slope.
