Abstract

 In this work, the vertical propagation of an SV shear pulse wave in a saturated homogeneous and horizontal soil layer under undrained conditions is analysed. Nonlinear constitutive models of variable complexity are used showing their influence on the modification, through the soil layer, of the input pulse applied at the rigid soil base.
