Influence of soil properties on amplification of saturated inhomogeneous poroviscoelastic soil profile

Toufiq Ouzandja, Mohamed Hadid

Abstract

The influence of local geotechnical site conditions on the soil profile amplification is analysed in this paper by assuming that the incoming seismic waves consist of inclined P-SV waves. The inhomogeneous soil profile is idealized as a multi-layered saturated poroviscoelastic medium and characterized by the Biot’s theory with a shear modulus varying continuously in depth according to the Wichtmann’s model. The results are presented in terms of horizontal and vertical soil profile amplification with linear and nonlinear soil behaviour, for different values of incidence angle, pore-water saturation, porosity, permeability, coefficient of uniformity, and non-cohesive fines content.

Keywords
Biot’s theory, Amplification function, nonlinear soil behavior, inhomogeneous soil profile.
