摘　　要：通过对10000 m3真空球罐光壳和带加强肋不同方案的外压稳定性分析,结合经济性对比分析,确定10000 m3真空球罐球壳结构采用光壳结构;阐述了该球罐的外压工况的有限元分析结果。By analyzing the stability of external pressure of the 10000 m^3 vacuum spherical tank without strengthening ribs and with different strengthening ribs, then comparing with the expense of the different constrnctions,reaching a conclusion that designing a 10000 m^3 vacuum spherical tank without stiffening ribs is a better plan than designing with ribs ; elaborating finite element analysis results of external pressure of this spherical tank.
