The wave field and dispersion equations are established for the porous layer surrounded by two elastic half-spaces. The porous layer is described by the effective model of the medium in which elastic and fluid layers alternate. In order to investigate the normal waves, all real roots of dispersion equations are determined and their movements with increasing wave number are investigated. As a result, the dispersion curves of all normal waves are constructed and dependence of the normal waves on the parameters of the porous layer and the elastic half-spaces is analyzed.
