The power intake of Gongboxia Hydropower Station is of the water-retaining structure.After the reservoir is impounded and oper-ates, the monitoring data of the inverted plumb of the power intake No.5 are found abnormal.To analyze deeply the abnormal data which shows the displacement of the monitoring point of the inverted plumb at the power intake No.5 toward downstream is a little great, whether possibility of deep sliding resistance and causes of the greater displacement toward downstream are analyzed from the geological conditions of the foundation at the power intake dam section and with help of value method as well.%公伯峡水电站进水口为挡水建筑物，水库蓄水运行后，发现5号进水口倒垂观测值有异常现象；为了深入分析5号进水口倒垂观测点向下游变位较大的原因，本次从分析进水口坝段基础地质条件着手，并借助数值方法，分析是否存在深层抗滑的可能性和向下游水平变位较大的原因。
