摘　　要：功果桥电站左岸边坡区域安装多个监测设备及仪器,2019年7月至11月,左岸边坡监测成果显示多支多点位移计测值变化速率增大,且变化趋势明显。对此,首先对左岸边坡布置的仪器、表观点、水位孔开展检查,进行仪器鉴定,判断仪器状态和数据有无失真,然后到电站现场进行边坡勘察及分析。结果表明:边坡混凝土喷层表面未发现开裂现象,锚墩头周边未发现变形开裂迹象,内部钻孔成像清晰,与前期地质勘测成果相吻合。Several monitoring equipment and instruments are installed in the slope area on the left bank of Gongguoqiao Hydropower Station.from July to November 2019,the monitoring results of the left bank slope showed that the change rate of the measured values of multi branch and multi-point displacement meters increased,and the change trend was obvious.Firstly,the instruments,surface views and water level holes arranged on the left bank slope were checked,and the instruments were identified to determine whether the instrument status and data were distorted.Then,the slope survey and analysis were carried out at the power station site.The results show that no cracks are found on the surface of the slope concrete shotcrete layer,no signs of deformation and cracking are found around the anchor pier head,and the internal borehole imaging is clear,which is consistent with the previous geological survey results.
