What are the factors affecting the total mean pressure in a soil medium amidst an earthquake excitation?

30 November 2018 1 6K Report

Hey There.

Assuming that the Mohr-Coulomb shear failure envelope as an elastic-perfectly plastic soil constitutive model is employed in FLAC3D. Referring to the dynamic section of the aforesaid software manual, the liquefaction analysis is able to be conducted throughout the Martin et al. equation. It is crystal patent that the dynamic pore-water pressure is totally different from the MC model to the other one. My question is how to interpret the changes in the total mean pressures such that the effective mean pressure in the liquefaction model is more or less the same as the one, derived from the MC soil model?
