Numerical analysis of saturated-unsaturated seepage flow In Fractured rock Mass due to surface infiltration

摘要

Seepage flow in fractured rock mass due to surface infiltration is a saturated-unsaturated seepage process. Aimed at rock mass with large fracture density, which can be Equivalent to continuum, a mathematical model for saturated- Unsaturated seepage flow in fractured rock mass due to surface Infiltration was established in this paper. The Galerkin finite Element method was used in numerical simulation and a finite Element program used to calculated saturated-unsaturated seep- Age flow due to surface infiltration was worked out. A model Experiment was employed examine the reasonableness of the Program.
