| 摘 要： | 介绍了储罐标准规范GB 50341、JIS B 8501、BSEN14015及API 650的罐壁厚度计算公式；比较分析了4个标准规范在罐壁厚度计算公式、罐壁钢板许用应力、罐壁焊接接头系数方面的差异.通过比较分析发现,除了许用应力、焊接接头系数不同外,罐壁计算厚度的设计液位高度也不一样,对设计液位高度的不同理解是引起罐壁厚度差异的主要原因.分析结果表明：采用GB 50341与采用其他储罐标准规范中罐壁厚度计算公式确定的罐壁厚度是一致的.为使罐壁计算厚度与国际标准规范相同,给出了许用应力的确定原则,同时重新定义了设计液位高度.通过实例证明,许用应力的确定原则是合理可靠的.

| Abstract: | This paper introduces tank wall thickness calculation formulas in tank technical codes （GB 50341,JIS B 8501,BS EN 14015 and API 650）,and comparatively analyzes the differences of the 4 codes in tank wall thickness calculation formulas,the allowable stress of tank wall steel sheet and tank wall welded joint efficiency.The comparison results show that besides the differences in allowable stress and welded joint coefficient,design liquid level height of tank wall calculation thickness is also different,and the main factor causing tank wall thickness variations is the different understandings for design liquid level height,and moreover,the tank wall thickness calculated using the relevant calculation formulas given in GB 50341 and other tank codes is consistent.In order to make the calculated tank wall thickness in line with the international standards and codes,allowable stress determination principles are given,and design liquid level height is re-defined in this paper.It is proved through field cases that the determination principles are reasonable and reliable.（6 Tables,4 References） |
