In-plane vibrations of soil deposits with variable shear modulus: I. Surface waves

摘要: The propagation characteristics of dispersive SV/P surface waves are analytically studied in a linear-elastic, isotropic, compressible half-space with constant mass density and Poisson's ratio shear modulus increasing according to continuous, bounded function depth. Dispersion relations for the particular wave modes evaluated over wide ranges parameters involved. Displacement profiles presented typical values these parameters. Finally, an equivalent depth is given use connection steady-state vibration techniques site investigation. (A)
