【摘要】 大型冷却塔是典型的风敏感结构,其抗风安全性直接关系到国家电力系统运行的可靠性。本文介绍了国内外大型冷却塔的建设现状,综述了大型冷却塔风洞试验、表面风荷载、风振响应、等效静力风荷载和风致振动控制等几个方面的研究进展;在此基础上并结合国外主要冷却塔设计规范指出我国大型冷却塔抗风设计相关规范条款的不足,建议需要进一步研究的若干新问题。从而可为在建或拟建的火(核)电超大型冷却塔工程提供一定的理论基础和设计指导,同时为超大型冷却塔的风致振动控制设计与实现提供重要的参考。更多还原

【Abstract】 Large cooling towers are typical wind sensitive structures,and the wind resistance safety directly determines the reliability of national electric power system.The status quo of development for large cooling towers are introduced in the paper,and the researches advances of wind tunnel tests,surface wind loads,wind induced responses, equivalent static wind loads and vibration control are summarized;on this basis the shortages for the standards of designing large cooling towers in our country are pointed out according with foreign relative design specification,and the new problems on wind resistance researches are proposed.The conclusions may supply the theory basis and designing guide for large cooling towers in China,meanwhile provide the important references of the design of wind induced vibration control system.更多还原
