DISPERSION TABLES FOR RAYLEIGH WAVES ON A SINGLE SURFACE LAYER.

Tables are presented to show the dispersive characteristics for Rayleigh waves on a single elastic layer overlying a uniform elastic half-space. Two standard models are considered, each specified in terms of four parameters: Poisson's ratio in the layer and in the half-space, and the shear velo...

Description
Summary:Tables are presented to show the dispersive characteristics for Rayleigh waves on a single elastic layer overlying a uniform elastic half-space. Two standard models are considered, each specified in terms of four parameters: Poisson's ratio in the layer and in the half-space, and the shear velocity and density ratios. Each parameter is varied through eight values, holding the other three parameters constant. For each such structure, results are given for the fundamental Rayleigh mode and the first and second shear modes. The tables consist of 32 cases, for each of three modes, for each of the two standard models, or a total of 192 tables. A special computation procedure for group velocities is used which eliminates the errors associated with the usual finite-difference approximation. Auxiliary information includes a tabulation of long-period cutoff values as a function of structure parameters. To illustrate the results for specific geologic and laboratory models, 36 additional tables are given. These include results for a continental ice cap, a continental crust, a sedimentary basin, an alluvial overburden, various two-and three-dimensional seismic models, and a case selected from the literature.
