Abstract: Focused on stationary seepage in porous medium of river dike,dam and bulkhead of highway the Laplace equation for solving seepage problem is transferred to the boundary integral equation mathematically in this paper,and then it is dispersed to the linear equation group and worked out using the FORTRAN programmed by boundary element.The results show that the method boasts the superiority to the finite element by its shorter time use of CPU,without meshwork,solution simplification and closer to the practical situation.
