摘　　要：针对内蒙古呼和浩特抽水蓄能电站上水库库底沥青混凝土防渗面板渗水的问题,通过水下录像检查和水下探摸示踪检查,发现了面板裂缝。采用嵌填止水填料、盖片封闭等措施对裂缝进行水下修复后,廊道渗水量明显减少,直至呈干燥状态。实践证明,该次水下探摸检查及水下沥青混凝土裂缝修复方法,可有效处理沥青混凝土面板局部裂缝问题。Research on the seepage of asphalt concrete anti-seepage panel at the bottom of the upper reservoir is conducted in Inner Mongolia Hohhot Pumped Storage Power Station and the cracks in the panel are found through underwater video inspection and underwater exploration and tracking.The cracks are not repaired underwater by filling the water stop material and sealing the cover until they are dry,and the rate of water leakage in the corridor is reduced obviously.The underwater exploration and inspection and the underwater repair of cracks in asphalt concrete in Hohhot Pumped-Storage Power Station provide a good reference for seepage treatment of the similar projects.
