| Abstract | This work presents numerical calculation models the influence of mechanical
properties of soil materials in the deformation analysis of ground and soil structures. The
transient response behavior of seabed to sea wave loading is a target problem of this
study. Since soil is multi-phase material, there are some variations for modeling soil
depending on problem and analytical conditions. Four types of constitutive model: u-w-p,
u-p, u- and w-p models are selected. In each model, numerical solutions are developed by
using finite difference method (FDM) in static, and quasi-dynamic both in 1-D with finite
depth and 2-D with infinite depth. For comparative examination of calculation results, the
applicability of each type modeling is discussed regarding influence factors such as
frequency, permeability and degree of saturation for different types of soils. Results of
numerical model are verified by compare with analytical solution for different
constitutive modeling and conditions. Good agreement between analytical solution and
nume1ical solution is observed for most of the constitutive model and conditions. The
results of this study suggest that the wave loading on a permeability seabed can alter the
effective stress state throughout the bed and may affect the stability of bottom sediments. |
