| Abstract: | The new five-point element scheme of finite analytic method for Laplace equation in irregular domain is used to calculate the constant seepage flow in heterogeneous dam body. The 5-point scheme of finite analytic method is given to simulate the unsteady seepage flow. The calculated result fitted well with the one obtained by finite element method. It shows that the five-point element scheme of finite analytic method can be used well to simulate the seepage flow. |
