Abstract
This paper studies dispersion of a Gtype earthquake wave under the influence of a suppressed rigid boundary Inside the Earth the density and rigidity of the crustal layer and the mantle of the Earth vary exponentially and periodically along the depth The displacements of the wave are found in the individual medium followed by a dispersion equation using a suitable analytic approach and a boundary condition The prominent effect of inhomogeneity contained in the media the rigid boundary plane and the initial stress on the phase and group velocities is shown graphicallyProject supported by the National Natural Science Foundation of China No 11471087 the China Postdoctoral Science Foundation No 2013M540270 the Heilongjiang Postdoctoral Foundation No LBHZ13056 the Support Plan for the Young College Academic Backbone of Heilongjiang Province No 1252G020 and the Fundamental Research Funds for the Central Universities
