Influence of Soil Permeability on Vertical component Influence of Soil Permeability on Vertical component

In this paper using governing equations of saturated porous media and using Newmark direct integration method a solution of wave propagation problem in saturated soils is presented. Results of this study can be used for analysis of pressure wave propagation through saturated soils during earthquake. In order to study effect of permeability on seismic response of saturated soil, response of deposits with different permeability coefficients is computed. Results show that a decrease in permeability has a damping effect on acceleration, whereas, amplifies the excessive pore pressure.
