Sand stiffness under various triaxial stresses
In many foundation vibration problems, such as vibration of machine foundations, supporting soil was first subjected to static stresses caused by weight of installation and then small amplitude vibratory stresses were applied; experimental data are presented to show effect of various static states of stress on dynamic shear modulus of dry sand measured by vibration and on static shear modulus measured by repeated torsion tests; stiffness of sand was found to be independent of deviatoric component of initial static state of stress and independent of rate of loading; effect of stress history was small; equations for computation of shear modulus, for use in design, from value of isotropic component of static stress and void ratio are presented.
