This report summarizes results of a combined experimental theoreticalnumerical study of the response of multiphase porous media subjected to high intensity static and dynamic loads. Theoretical models for fully coupled porous skeletons subjected to static and dynamic loads are developed for saturated and partially saturated conditions. These theoretical models are incorporated into numerical codes which are used in a systematic study of multiphase response which includes modeling of liquefaction in saturated soils and rocks wave propagation in saturated porous media, including modeling of compressional waves of the first and second kind and the role of pore fluid in damping, wavespeed and liquefaction as a function of the material properties of the porous skeleton.
