Based on the two-parameter elastic foundation model, the dynamic equations of the infinite beam with two-parameter viscoelastic foundation taking into account the deformation with time are deduced. The dynamic equations are solved by using the direct integral method and the Green’s function respectively. The solutions of the two methods are compared to verify the solving process The correctness of each beam is discussed. The integral form solutions of corresponding beam deflections are obtained under different dynamic loads.
