采用超声波技术对王甫洲电站流道顶板混凝土进行无损检测，在检测成果分析和评价基础上，对混凝土缺陷采取了“喷混凝土+环氧砂浆抹面”的补强加固措施。质量检查表明，处理效果较好，满足结构安全和工程运行要求。

Scatheless acoustic sounding was applied to detect the concrete defects in the top cover of entrance zone of the workshop at Wangfuzhou Hydropower Station. On the basis of analyses and evaluation to the results of investigation, such treatments as shotcrete and epoxy mortar to repair the concrete defects were adopted. Quality detected result indicates that the effect of treatments on concrete defects is good and it can satisfy the operation requirem
ent of the project. 
