Subgrade stress and deformation under dynamic load
Experimental investigation to determine complete pattern of dynamic stress, strain, and surface deflections in clay subgrade material subjected to uniform surface contact pressure applied over circular area is described; this is first stage in major research project, aim of which is to obtain comprehensive information on stress and deformation in three-layer pavement structure under dynamic load; details of calibration tests on transducers for measuring in-situ stress and strain are described; results indicate stresses to be predicted adequately by elastic theory, but that strains, being dependent on soil modulus, are less well predicted; at low stress levels encountered, soil stress-strain curve is markedly nonlinear.
