About asymptotic analysis of wave fields in layered-inhomogeneous environments
Incoming article date: 28.11.2013The application of asymptotic analysis method for displacement fields in environment is considered on the basis of special representation of motion equation solutions for multilayered half plane in the case of steady vibrations. The large parameter in suggested research method is distance from force source to supposed view point with glance of wave re-reflection from layer boundaries. The results of numerical simulation is given and the conclusion about the effectiveness of suggested method for construction of asymptotic expansion is given.
