Abstract:

The motivating philosophy for a rheologic study of the dynamic response spectra of soils is pre sented. Basic concepts regarding the method of approach, equipment development, experimental techniques, preparation and control of soil specimens and preliminary results of the soil response under various loading conditions in uniaxial compression are given. Dynamic visco elastic techniques are utilized and the linear and nonlinear aspects of soil response under dynamic and static loading conditions are studied. The variables considered include dynamic stress level, dynamic strain level, strain rate, static stress level, tim of loading, frequency of load application, phase angle, quasi-static strains, strain recovery, moisture content, density, un confined compressive strength and specimen geometry.
