Abstract
The microscopic model TRUBAL was modified and used to study solid pore fluid interactions. The influence of pore fluid on the granular assembly was modeled by introducing the Reynolds equation based on theory of hydrodynamic lubrication. The Reynolds equation is solved using finite difference method for each contact using the particle velocities computed from TRUBAL. At any time increment, drag forces and equivalent upthrust values due to the localized pore pressures are calculated using Reynolds equation for the particle motions resulted from the earlier time increment. Modified TRUBAL for saturated soils was used to simulate triaxial tests. Numerical triaxial simulations using the modified TRUBAL program produced treads similar to the physical tests.
