（中國礦業(yè)大學力學與建筑工程學院，徐州221116）[摘要] 徐州某火電廠水泵房建成于20世紀70年代末期，由于服役時問較久，構筑物已有一定劣化、破損。考慮到水泵房后續(xù)使用的安全性，對該構筑物主體結構的工作環(huán)境、外觀質量、鋼筋混凝土構件的混凝土碳化深度及抗壓強度、鋼筋分布和保護層厚度、鋼筋銹蝕等進行了全面的檢測，并依據(jù)相應的檢測結果及規(guī)范對其主體結構進行了設計復核。在此基礎上，對水泵房主體結構的安全性進行了綜合評定，并提出了相應的修復加固與維護建議，可供同類工程參考。

( School of Mechanics＆Civil Engineering, China University of Mining and Technology, Xuzhou 221116, China)Abstract: Water pump house of a thermal power plant was built in Xuzhou at the end of 1970s. A certain degree of deterioration and damage has occurred to the structure because of the long service time. Taked the subsequent use of safety into account, the main structure was completely detected. The detection content included service environment, appearance quality, carbonation depth and compressive strength of concrete, distributions of reinforcement and cover thickness, steel corrosion ratio and so on. A design check about the main structure was made according to the corresponding detection results and standards. On these basis, the safety of the main structure of water pump house was comprehensively assessed, and some suggestion about repairing, reinforcement and maintenance was provided. It can be referred by similar engineering.
