Analysis of embankment underlain by elastic half-space: 2.5D model with paralongitudinal approximations to the half-space

This article presents a set of close approximations to model an elastic half-space supporting an embankment, which are evaluated in the context of phase velocity spectra, i.e. in terms of the normal wave propagation modes of the embankment-half-space system. The ultimate, intended target of these approximations is in the modeling of...
