摘　　要：以三次B样条函数为试函数,计算了在轴对称线荷载作用下夹层扁球壳的非线性弯曲问题.夹层板壳采用Reissner模型.将固定夹紧夹层圆板的结果同摄动法解的结果进行了比较.本文的数值结果有很高的精度.Cubic spline taken as a trial function, under action of axisymmetric line load, nonlinear bending of shallow spherical sandwich shells was calculated. A sandwich plate or shell was assumed to be Reissner＇s model. Results of circular sandwich plates with rigidly clamped edge were compared with those obtained by the perturbation method. All numerical solutions are with high precision.
