摘　　要：齐热哈塔尔水电站调压井后边坡坡高107 m,综合坡比1:1。边坡岩体以薄层状板岩为主,且呈碎裂镶嵌结构。利用施工期地质编录的成果,采用宏观判断和赤平投影的方法对边坡的整体稳定进行了分析,得出了边坡整体稳定,但存在局部崩塌或垮落的可能,同时提出了采取适当的加固措施,做好排水并加强监测的建议。The back slope of Qirehata'er hydropower station surge shaft is 107 m high,its comprehensive slope ratio is 1:1.The rock mass is mainly thin bedded slate of fractured mosaic structure.According to the geological logging results in construction period,macro judgment and stereographic projection methods are used to analyze the overall stability of slope,and make sure its stability,but there is potential of local collapse or collapse,therefore,it put forward the suggestion of taking appropriate reinforcement measures,and strengthening drainage and monitoring.
