摘要：Corrosion problems of outdoor concrete facilities was summarized through research on coastal substation of Fujian, such as serious corrosion of steel ring and weld in the joints of cement poles, exposure and corrosion of reinforcement, cracking and falling off of concrete cover. The information of concrete facilities’ assessment reports was summarized, and it was found that concrete compressive strength of present age satisfied early design drawings. In addition, appraisal of reliability revealed that all facilities couldn’t satisfy the requirements of current standards and seismic appraisal revealed that all facilities couldn’t meet the seismic requirements. The analysis of concrete facilities’ corrosion mechanism was made, and it was found that concrete facilities in coastal substation suffered triple effects of carbonation, chloride corrosion and stray current corrosion. The power failure schemes needed for present repairing and strengthening measures of concrete facilities lack of feasibility. Research on repairing and strengthening measures of concrete facilities that requiring no or small-scale power cut would be of great significance.
