Dynamic constitutive relation and dynamic modulus attenuation model of red clay

In view of the dynamic stability of red clay subgrade under high-speed traffic cyclic loading,the dynamic constructive relation and attenuation laws of dynamic modulus are studied through a series of cyclic triaxial tests on red clay in original structure.The test results show that the dynamic constitutive relation of red clay in original structure can be described with the hyperbolic curve model presented by R.L.Kondner,dynamic modulus of it reduces nonlinearly with the accretion of dynamic str...
