摘　　要：铜街子水电站位电站左岸边坡为一古滑坡体,为了准确掌握左岸古滑坡的稳定状态及复活的可能性,有必要对滑坡体的形成条件、滑坡过程及滑动方式进行研究。同时,结合滑坡体GNSS监测数据和水准控制网测量数据对滑坡体的变形情况进行分析,结果表明,滑坡体上部虽然存在缓慢向下的趋势,但近5年内左岸边坡各点平均变化量都小于1mm,变化较为缓慢,基本处于稳定状态,但后期仍然需要密切关注其变化。The left bank slope of Tongjiezi Hydropower Station is on an ancient landslide accumulation.In order to accurately grasp stability status of the ancient landslide on the left bank and the possibility of resurrection,it is necessary to study the formation conditions,process of and the sliding mode of the landslide.Meanwhile,deformation of the landslide accumulation is analyzed based on GNSS monitoring data and leveling control survey data.The analysis results show that the upper part of the landslide body has a slow downward trend,but the average change of each point of the left bank slope is less than 1mm in the past 5 years,the changes are relatively slow and it is basically in a stable status,but it is still necessary to pay close attention to the changes in the later period.
