摘　　要：以混合样条函数作为位移函数，考虑了圆屋顶与顶部环梁及底部环梁变形协调关系，导出了全部必需的公式。进行了例题计算，所得结果与已有文献结果非常接近。本文方法具有自由度少、占计算机内存少、计算速度快等优点。Taking the mixed spline function as the displacement function of revolutional shell and considering the deformation compatiblity between the revolutional shell and the top ring beam or the bottom ring beam, all the necessary formulas are derived. Some examples have been calculated, the results are very close to that of other papers. The proposed method possesses advantages of less degree of freedom, less storage required in computer and rapid computation.
