摘　　要：公伯峡混凝土面板堆石坝周边缝变形监测中发现,右岸周边缝测缝计测值在蓄水期变化较大,且呈趋势性变化,部分测点开合度和面板法向错动超了设计控制值。为此,2011年进行了水下检查,发现周边缝变形较大部位面板混凝土存在缺陷,随即对缺陷进行了封堵处理。笔者对混凝土面板周边缝变形进行了分析,介绍缺陷处理情况,并对处理效果进行了评价。By monitoring on the deformation of peripheral joint, it was found that the monitored value forthe right bank varied widely during storage and formed a trend. Moreover, the opening at some monitor-ing points and the normal displacement were larger than the designed value. Underwater inspection wascarried out and the defects on concrete face slab were found. The paper introduces the deformation of pe-ripheral joint and the treatment. As well, the treatment effect was assessed.
