摘　　要：在考虑竖向附加力作用时，井壁结构的设计计算应按空间轴对称问题考虑。在运用迭加原理求得了井壁应力的计算公式后，又编制了空间轴对称问题的有限元程序，通过计算发现，两者的误差很小，都可应用于井壁结构的设计计算。The calculation made a design for shaft wall structure under vertical addition force should consider the problem of space axially symmetry.The calculation formula of shaft wall stress is obstained by applying repeated addition principle.The finite element program for the space axially symmetry is given.As a result of calculation,the errors between the repeated addition principle and axially symmetry finite element program is almost the same.So both of them can be apply to calculate the shaft wall structure design.
