Abstract: In order to keep the safety of the earth dam, the seepage characters of the earth dam should be analyzed in the hydraulic engineering and the free surface should be determined firstly. According to Darcy’s law, seepage constitutive equations, water head and flux boundary condition, a model is established for the seepage in the in homogeneous earth dam on imperviousness groundwork. By the Geoslope software, the free surface of the earth dam is calculated using the finite element method, and the change of the free surface is analyzed when the permeability of the earth dam is changing. At last, the numerical simulation of the free surface is verified by an analytical solution.

Key words: homogeneous earth dam on imperviousness groundwork, free surface, dividing segments method, two dimensional finite element method
