This paper deals with interaction between nonlinear geo-medium and non-circular structure due to transient wave. The behavier of the geo-medium is described by the nonlinear e-lastic model with multiple parameters. The analytic solutions of the asymptotic equations of each order obtained by small parameter perturbation are given by the complex function method. Numerical computation is simplified by the mapping function. The numerical results of displacements and stresses of arch-wall structure dymanic response to the horizontal and vertical incident transient wave are given in the paper.
