Abstract: Although the finite-difference method (FDM) has been commonly used to numerically solve Richard’s equation, numerical difficulties are often encountered, even for comparatively simple problems. To minimize convergence ...

Abstract: Richard’s equation governs the migration of moisture in the soil under unsaturated conditions. Although this differential equation provides a rigorous approach to simulating important infiltration problems, obtaining ...

Abstract: This paper presents finite-element analyses of excavations by using a coupled deformation and flow formulation. Specific numerical procedures were implemented into the finite-element codes to simulate the excavation ...

Abstract: The main objectives of this research are to investigate the effect of hydrated lime (HL) treatment on the swelling behavior of a natural expansive soil, Eagle Ford clay from Texas, through centrifuge testing. So far, no ...

Abstract: This paper presents the results of an elastoplastic finite-element back analysis of an excavation made on a saturated soft organic clay deposit in Rio de Janeiro, Brazil. The excavation was conducted as part of an urbanization ...

Abstract: This study presents a novel three-dimensional (3D) analytical solution to the Richards equation, which takes as a basis a linear unsaturated model that was previously proposed. Specifically, the partial differential equation ...
