| Abstract: | In this paper, the FEM is adopted to simulate 3 D saturated unsatuated unsteady seepage field, the linear equation set representing the seepage field is solved by preconditioning conjugate gradient method, and the computer code named as US3D is compiled in FORTRAN. Through the case examples and practical application, it is proved that the US3D is of wide applicability, easy to operate, and the simulated results are reasonable. Using this code, the simulation of the saturated unsaturated seepage field in the mountainous areas under heavy rainfall condition may be performed. |
