摘　　要：富春江水电站运行40多年,电站开关站混凝土构架出现混凝土剥蚀和裂缝。针对实际情况,对混凝土构架进行无损检测,检测内容包括凝土裂缝深度、混凝土强度、混凝土碳化深度、构架内部钢筋保护层厚度和构架内部钢筋锈蚀检测等,并根据检测的情况提出了补强加固方案。该技术对于水电站混凝土构架的检测和加固具有一定指导意义。Fuchunjiang hydropower station has run for more than 40 years, Switching station concrete frames emerge denudation and crevices. In terms of the actual situation, we detect concrete frames with nondestructive testing method, and testing content including fissure depth, concrete strength, carbonation depth, depth of cover to reinforcement, corrosion testing of reinforcement, etc. we come up with reinforcement scheme on the basis of testing report. The technology must have guiding significance to certain for concrete frame in hydropower station.
