摘　　要：本文采用半解析方法研究在中心分布载荷及中心集中力联合作用下,圆底扁球壳的非线性稳定性问题.避免了求近似解析解时繁重的人工计算,而p-W_m特征关系仍可由显式表达.Using a semi-analytical method, the nonlinear stability of a spherical shallow shell under centrally distributed and concentrated loads is investigated in this paper. The longer manual calculation has been avoided when finding the approximate solution, and the p-Wm characteristic relation can be given analytically.
