A Chebyshev Spectral Elements Method for Earth Dam Seepage Analysis

Based on the theory of spectral elements method,this paper theoretically analyzed the issue of earth dam seepage under both one-dimensional and two-dimensional conditions. First,an integral form about the seepage problem was set up;then,the discrete matrix equations were formed by using Chebyshev polynomials as the basis function and the global coefficient matrix was formed in the way used in the finite-element method.Finally,according to different types of boundary conditions,water head linear array {h} was calculated and the whole dam's water head was educed from this linear array.

Key words:Spectral elements method,seepage,Chebyshev Polynomial,finite element method
