一、前言:油罐浮顶单盘是重要特殊部件,计算方法比较复杂。参考文献中指出,油罐的经济尺寸需要根据地基条件决定,改变油罐尺寸就需核算单盘的强度和紧急放空管安装高度。利用浮船安装罐壁时也需计算单盘强度。所以,无论是设计工作者或现场施工人员都需要了解单盘的正确设计计算方法。国内比较完整的单盘计算方法是由中国科学院力学研究所(以下简称力学所)于1965年提出的。1972年国内报导了国外某些设计公司采用的计算方法。力学所把单盘看成是固结在弹性边环上的薄膜来计算的。国外
First, the preamble: Single tank floating roof is an important special component, the calculation method is more complicated. References pointed out that the economic size of the tank needs to be determined according to the foundation conditions, the size of the tank need to be calculated on the strength of a single disk and emergency vent tube installation height. When using pontoons to install the tank wall also need to calculate the strength of a single disk. Therefore, both designers and field workers need to understand the correct design and calculation of single disc. The relatively complete single-disc calculation method in China was proposed by Institute of Mechanics, Chinese Academy of Sciences (hereinafter referred to as “Institute of Mechanics”) in 1965. In 1972, China reported the calculation methods used by some foreign design companies. The mechanics treats a single disc as a thin film that is attached to a flexible edge ring. foreign
