摘　　要：冷却塔是电厂的重要配套项目之一,其结构具有高大、薄壁、变径、变截面、曲面等特点,施工难度大,高空作业多,工艺技术要求高,工程影响广,而且结构形式又大致类似,因此以双曲线冷却塔为例,从环形基础、人字柱和筒身三大重点工序分析施工重点,总结施工难点和相应处理措施,提升施工控制水平。Cooling tower is one of the important supporting projects of power plant,and its structure has the characteristics of tall,thin wall,variable diameter,variable cross-section and curved surface.It has big construction difficulty,high altitude work,high technical requirements,extensive engineering impact,and similar structural forms.Therefore,taking the hyperbolic cooling tower as an example,the construction key points are analyzed from the three key processes of the ring foundation,the herringbone column and the barrel body,and the construction difficulties and corresponding treatment measures are summarized to improve the construction control level.
