Sumario: | The main goal of the present paper is to present a mathematical framework for modelling
multi-phase non-saturated soil consolidation with pollutant transport based on stress
state configurations with special emphasis in its versatility. Non-linear saturation and
permeability dependence on suction for both water and pollutant transport is regarded.
Furthermore, through the introduction of a suction saturation surface instead of simple
suction saturation curves, the implementation of the saturation–suction coupling effect
is considerably simplified. The achieved differential equation system is discretized within
a Galerkin approach along with the finite element method implementation. A widespread
set of practical situations is encompassed by simply setting certain coefficients of the
discrete system of equation according to concrete problem conditions. When the model
is coped with certain selected fringe conditions, the approach adaptability feature came
up showing a robust performance. |
