Sh waves in two layered systems: the relationship between the surface phase velocity and the frequency

The phase velocities of horizontally polarised shear waves (sh waves) at the free surface of a layered structure are dispersive. The measured values of the phase velocity can be compared with those calculated for an idealised layered structure. When a match is obtained, the properties of the actual and hypothetical layered structures are assumed to correspond. A system consisting of two layers each of constant thickness, overlying a medium of large depth, represents a common model of a pavement structure. Mathematical expressions are presented which facilitate the calculations needed in analysing some structures of this type (a).
