摘要
根据烟囱设计规范中对塔架式烟囱风荷载体型系数取值的结论,以某重油电厂四筒塔架式烟囱为例,对风向与塔架迎风面正交工况和风向与塔架迎风面斜交两种工况分别计算并进行对比分析,得出了塔架式烟囱设计计算时,风荷载应取两种工况的包络值,并提出了实际工程设计的合理化建议,可供类似工程参考。
According to the conclusion of the chimney wind load shape coefficient in code for chimneys design, taking the four-tube tower chimney of a heavy oil power plant as an example, two working conditions of orthogonal and oblique to the windward side of the tower are calculated and compared. Results shows that the wind load should take the envelope value of the two working conditions when the tower chimney is designed and calculated. Some proposals for the actual engineering design are given,so as to provide reference for similar projects.
