Abstract
Peaks of transient strains in a layer over semiinfinite half space are amplified byinterference during
up- and down-propagating waves, and they depend upon the impedance ratio of the layer and of the
half space, as well as the wavelength.The amplification of incident motion on the ground surface is
usually described in the frequency space for the response to a steady state, periodic excitation. To
understand how this amplification develops for transient responses and for applications in which the
linear theory leads to satisfactory answers, this paper describes the amplification in time in a layer
excited by a shear wavepulse. It is shown that the maximum amplification is equal to 2 for a ‘‘stiff’’ layer on a ‘‘soft’’ halfspace, and equal to 4 for a ‘‘soft’’ layer on a ‘‘stiff’’ halfspace, when the layer
thickness corresponds to the quarter wavelength of the wave in the layer.
