Abstract EN
A nonlinear flow relationship, which assumes that the fluid flow in the soil skeleton obeys the Hansbo non-Darcian flow and that the coefficient of permeability changes with void ratio, was incorporated into Biot’s general consolidation theory for a consolidation simulation of normally consolidated soft ground with or without vertical drains.
The governing equations with the coupled nonlinear flow model were presented first for the force equilibrium condition and then for the continuity condition.
Based on the weighted residual method, the finite element (FE) formulations were then derived, and an existing FE program was modified accordingly to take the nonlinear flow model into consideration.
Comparative analyses using established theoretical solutions and numerical solutions were completed, and the results were satisfactory.
On this basis, we investigated the effect of the coupled nonlinear flow on consolidation development.
