| Abstract: | In order to improve the finite element analyses of saturated-unsaturated seepage, some new methods was put forward in this paper, such as the method of revising water capacity and the technique of accelerating iterative convegence, which can be used to avoid the numerical dispersion in the calculation of saturated-unsaturated seepage so as to raise the convergence speed. Examples were given to prove the theoretical validity of presented methods. |
