In this paper, the ground motion of an isosceles triangular dike impacted by SH waves is discussed. The methods of complex function and moving coordinate system as well as a simple model are used here. At first the model is divided into two parts based on the method of division and assistant function, a wave function which satisfies the condition of stress free at the triangular wedges is constructed in one part, a scattering wave function which satisfied the condition of stress free at the horizontal surface is constructed in another part. And then the moving coordinate system is used to solve the problem. The solution of the problem is reduced to a series of algebraic equations and obtained numerically. Finally the numerical examples are provided to show the substantial differences between what we acquired and what showed in article[ 9].
