介绍一种具有优良结构韧性和稳定性，耗钢量低，制造方便的大直径油罐的固定顶盖。近几年，在国内已有３０多台直径为３７～４６ｍ的内浮顶油罐及固定顶油罐采用了这种结构。同时介绍这种网壳顶的结构特点、力学性能及３种中型模型试验的结果。由于理论计算与实测结果比较符合，罐顶板的排板及网壳杆件及其连接均采用省工、省料的构造，使这种结构不但计算可靠，而且具有优良的技术经济指标。
A fixed roof with a large diameter tank with excellent structural toughness and stability, low consumption of steel and easy manufacture is introduced. In recent years, more than 30 domestic floating roof tanks and fixed roof tanks with a diameter of 37 to 46 m have been adopted in China. The structural characteristics, mechanical properties and the results of three kinds of medium model tests are also introduced. As the theoretical calculation and the measured results are in good agreement, the top plate of the roof plate and the shell and its connections are made of labor saving, material saving structure, so that this structure is not only reliable calculation, but also has excellent technical and economic indicators.
