Abstract :
The Differential quadrature method (DQM), which equals to high precision finite difference method, is able to obtain highly accurate numerical solutions of differential equations using less grid points. The numerical method is always used to solve the complicated one dimensional non-liner consolidation equation. The one dimensional non-liner consolidation equation and boundary conditions are discretizated by the polynomial based on quadrature method in this paper. Euler forward scheme is used to solve the discrete equation, the pore pressure and consolidation curves are prepared. The numerical and analytical results are compared in this paper. The results show that the method of solving non-liner consolidation equation by DQM is reasonable and the DQM can give the satisfied results with less grid points.
