摘　　要：针对广州抽水蓄能电站A厂地下厂房出现的裂缝,开展了检测和成因分析工作,并在此基础上完成了修复方案论证工作。最终选定了结构补强修复方案,即对施工缝附近、吊物孔周边及检测有裂缝的梁板进行补强修复处理,该方案具有对现有结构损伤小、不影响机电设备布置、工程投资省、施工难度相对最低、工期最短等优点。Cracks were found in the underground powerhouse of Guangzhou Pumped-Storage Power Station Plant A,the verification of strengthening scheme was finished which based on quality inspection and genetic analysis. Finally the structure strengthening as the repairing scheme was adopted,which reinforced the beams and floor slabs near the construction joins or hanging hole,and other parts cracks appeared. There are so many advantages about the structure strengthening scheme,such as small structure damage,no effect on equipment layout,low construction difficulty,small investment and short terms etc.
