摘要:
以参数分析为基础,对中、英、德双曲冷却塔结构设计规范静风稳定条款进行了对比,比较了整体稳定公式参数取值的差异和影响; 以多座不同高度的双曲冷却塔为例,分别采用中、英、德规范计算整体稳定和局部稳定因子。结果表明:当中国规范采用塔顶迎风点风荷载标准值作为整体稳定参考风压时,中、英、德规范得到的整体稳定因子才基本一致,整体稳定和局部稳定因子也在同一水平。
Abstract:
Based on the comparative study of parameters, DL/T 5339—2006(China), BS 4485-4:1996(British), VGB-R 610Ue:2005(Germany)were selected as the representative codes and the calculation principles and methods of aerostatic stability of hyperboloidal cooling tower structures were surveyed, especially for the differences of parameters for global stability and their influences. Several representative hyperboloidal cooling towers were taken as examples to assess the final distinction in global and local stability. The results show that the global stability factors agree well with each other and the factors from the global and local stability can also be in conformity if DL/T 5339—2006 takes the nominal value at the top of windward meridian as the reference wind pressure for global stability.
