In order to solve the problem that transfer matrix in axisymmetric dynamic problem of single soil layer overlaid on elastic half-space is ill-conditioned

the error analysis method is presented. The disposal method for integrand is discussed in three conditions; then the disposal method for the inverse-Hankel transformation and the inverse-Laplace transformation is briefly introduced. Based on these

the method how to decrease the error is presented. The analysis result is verified through the degenerating model. The result indicates that the method presented can effectively decrease error. All this work can provide idea for solve the problem that transfer matrix in axisymmetric dynamic problem of layered elastic half space.
