摘　　要：目前球-环-锥结构在外压作用下强度的计算有3种方法,即旋转壳有限元法、解析法和弹性基础法。重点介绍了这3种方法的基本假设及基本思路。对比各种方法的使用范围和局限性,弹性基础梁由于自身的优越性,是当今规范设计中球-环-锥结构的强度计算方法。There are three methods—rotational shells finite element method,analytic method and elastic foundation beam method for calculating the strength of sphere-toroid-cone combined shell under external pressure.The paper lay stress on the basic hypothesis and essential thoughts of these methods.Contradistinguished from another methods,elastic foundation beam method is the criterion calculating method because of its superiority.
