BOUNDARY ELEMENT ANALYSIS FOR FREE SURFACE OF SEEPAGE IN EARTH DAMS

The boundary element method is applied to study the free surface of unconfined water flow in earth dams. The soils are modeled as the porous media and the pore fluid flow obeys Darcy's law. A general multi-region boundary element method is developed to investigate the inhomogeneous dams. The fr...

Summary:The boundary element method is applied to study the free surface of unconfined water flow in earth dams. The soils are modeled as the porous media and the pore fluid flow obeys Darcy's law. A general multi-region boundary element method is developed to investigate the inhomogeneous dams. The free surface is analyzed directly by the trial and error method. Both homegeneous and inhomogeneous dams are fully studied, and the numerical results show satisfactory agreement with previous researches. The proposed numerical method possesses essentially the same assembly procedures as the finite element method, but with much less computer memory storage.
