［摘要］介绍了《工业循环水冷却设计规范》(GB/T50102—2003)和《火力发电厂水工设计规范》(DL/T5339—2006)中冷却塔静风局部稳定检算方法——屈曲临界应力状态的公式来源、试验背景以及参数取值原则等，便于设计研究人员正确理解和应用局部稳定检算公式。根据Mungan针对圆柱壳、双曲壳以及加劲双曲壳的一系列试验及与其他国家规范的比较，指出了现行规范中相关条款的缺陷，为规范条款的修订和完善提供了参考。

Abstract:Buckling stress state (BSS) approach used for local buckling design of hyperboloidal cooling towers in GB/T 50102—2003 and DL/T5339—2006 was introduced, including the source of related formulas, background experiments, principles for parameter values and so on. As supplement for our codes, the introduction provided an effective approach for the understanding and application by researchers and designers. Based on the background experiments carried out by Mungan and comparison between other codes, the defects of related specifications in our current codes were pointed out and suggestion was provided for the revision and improvement of our current codes.

Keywords:hyperboloidal cooling tower; code; buckling stress state; local buckling
