摘　　要：自然通风双曲线冷却塔的稳定性一直是其结构设计的重点关注的方面之一,其计算方法和计算手段的合理性与正确性直接关系到冷却塔的设计是否经济、安全、可靠。针对国内规范中对冷却塔稳定性的规定,本文阐述了目前在设计应用中遇到的若干问题,对相关的计算方法和建模方法进行了阐述,并结合实例说明这些问题,以及目前的解决办法。The buckling stability of natural draft hyperbolic cooling tower is always one of most important concern in design work. The rationality and validity of its calculation method concern the safety, economy, reliability of cooling tower＇s design. For the requirement about buckling stability in the native codes, some appling problems were demonstrated, the relevant calculation method and modeling method were elaborated, and then an example was given to illuminate these problems and how to deal with them.
