针对冷却塔施工运行过程中出现的施工缺陷、混凝土开裂和剥落、冻融酥松、风蚀龟裂、空气和雨水的酸蚀、湿热曝晒及干缩等温度应力造成的变形与破损现象，结合具体的工程实例，分析了这些破损产生和出现的内在原因，阐述了这些缺陷、破损的危害和影响。总结分析了喷浆加固、圈套加固、钢箍加固等维修及加固方案；针对不同类型的缺陷及破损，提出了修补技术措施，为冷却塔的维修加固提供参考。

For the cooling tower, the distortion and breakage will occur due to constructional deficiency, concrete cracking and spalling, freeze-thaw rarefaction, deflation cracking, acid etching of air and rainfall, and temperature stress by muggy insolation and shrinkage etc. The internal causes, harm and influence for the breakage are analyzed combining the project practice. The maintenance and reinforcement techniques are introduced including gunite reinforcement, trap strengthening, and bind reinforcement etc. Aiming at various flaws and breakages, new maintenance techniques are proposed, providing references for the maintenance and reinforcement of cooling tower.
