摘　　要：我国砌石坝众多,许多水库上游采用混凝土面板防渗,但很多面板存在质量和结构问题。通过提出闸墩向上游悬挑,增加上部荷载的方法,消除上游面板局部拉应力。然后通过有限元复核计算,与加固前对比,上游面板拉应力得到显著改善,可为其他水库除险加固过程中遇到类似问题提供参考。There are many stone DAMS in China, and many upstream reservoirs use concrete panels to prevent seepage, but many panels have quality and structural problems. In this paper, the method of overhanging gate pier upstream to increase the upper load is proposed to eliminate the local tensile stress of upstream panel. Then the finite element calculation shows that the tensile stress of upstream face plate is significantly improved compared with that before reinforcement, which can provide reference for similar problems encountered in the process of reinforcement of other reservoirs.
