摘　　要：全面介绍了工程上常见的一些罐顶结构形式,并对各自的结构特点、使用范围及应用情况进行了简述。通过分析认为,目前国内新开发的球面网壳顶,对容积在10000m^3以上的大型固定顶油罐具有一定的推广价值,但有几方面的问题应予以注意:此种罐顶结构的理论分析、设计计算和施工中的构件预制及罐顶安装等比较复杂,需要具备资格的单位来完成;选择技术可靠和实用性强的网格结构使之推广,并不断进行完善;对与使用安全有关的技术问题要给予足够重视。此外,对其它罐顶结构形式也应予以充分地考虑。This paper comprehensively recommends some forms of the roof structure which are frequently used in tank enginnering,and briefly describes their structural features, operating ranges and serviceable conditions. Through analysis,it is considered that a few lattice domes which have been developed by domestic manufacturing plants recently possess particular popularized value for large fixed roof tanks with a volume of 10 000 m3 and above. However,the following cases should be taken notice of ;the theoretical analysis Resign and calculation of these roof structures as well as the preparation of structural members and the installation of roofs at a construction site are comparatively complicated,and therefore the design and construction of these tanks need to be fulfiled by a qualified unit ;reliable and practical structures of the lattice dome should be selected so as to popularize and continuously perfect them;technical problems which are related to the safety application of these tanks should be paid enough attention to. In addition,other types of the roof structure should be taken into full consideration too.
