In this paper we consider the question of constructing wave fields in the problem of steady oscillations of an inhomogeneous over thickness poroelastic layer under the influence of load on the top face. The solutions of this problem, in the general case of inhomogeneous characteristics, can be constructed only numerically. Due to this fact the process of solving the problem is divided into three steps. The first step is the Fourier transformation over the longitudinal coordinate. The second step is the shooting method for constructing the solution in the transformants. In this step much attention is paid to the problem of stiff differential equations systems. And the final step is the numerical inversion of the transformation. The results of calculations of the wave fields for various values of the wave number and various irregularities are presented in the end of the paper.

Построены решения задачи об установившихся колебаниях неоднородного по толщине пористоупругого слоя под действием нагрузок на верхней грани. При решении применена комбинация преобразования Фурье, метода стрельбы и последующего численного обращения. Рассмотрен частный пример изменения неоднородных характеристик.
