FINITE ELEMENT ANALYSIS OF SATURATED-UNSATURATED SEEPAGE IN SOIL

Transient seepage model for saturated-unsaturated soil systems: a geotechnical engineering approach

A two-dimensional finite element model is proposed to simulate transient seepage for complex groundwater flow systems. The complete soil system is treated as a continuum encompassing flow in both saturated and unsaturated zones. In the unsaturated zone, the air phase is assumed to be continuous and open to atmospheric pressure. The coefficient of permeability of the unsaturated soil is assumed ...

Finite Element Analysis of Pipe Buried in Saturated Soil Deposit Subject to Earthquake Loading

A coupled stress-flow finite element procedure, based on dynamic Biot equations, was used to analyze the behavior of pipe buried in liquefiable soil. The governing equations, soil constitutive model, finite element discretization and solutions were described. The results of analysis were compared with two cases of dynamic centrifuge test of soil deposit and pipe conducted at 30-g acceleration f...

Seepage Analysis through Rockfill Dams by Finite Element Method in a Fixed Gird

In this paper, Forchheimer equation is used as the constitutive equation for flow through rockfill, and the non-linear two-dimensional governing equation with free surface is solved by a new finite element method in a fixed grid. The model is verified by applying it to different flow conditions. The first scenario, which is assumed to be one-dimensional with analytical solution available for it...
