Abstract
The dynamic response of a half-plane soil medium subjected to a moving load of constant velocity is resolved by considering the plane composed of a geometrically and physically linear micromechanical elastic granular media, obeying the doublet mechanics theory by Granik and Ferrari [1]. The parameters examined mainly include the load moving velocity effects on vertical deflection and stress fields in the half-plane. In addition, comparison was also made for the differences of stress fields obtained from the doublet mechanics and from the classical elasticity theory. It is concluded that the micro-stress fields in the half-plane that were calculated based on the doublet mechanics exhibit asymmetric pattern with respect to the moving load applying point instead of symmetric stress pattern calculated using the classical elasticity theory.
