Numerical Simulation on the Three-Dimensional Seepage Field of Zhelamuqing Tailings Dam

Abstract:

Based on the engineering geological, hydrogeological conditions and survey results of Zhelamuqing tailings dam, two types seepage problems in the tailings dam which are saturated seepage and saturated - unsaturated seepage were described and solved by Darcy law and Richards Equation respectively. Then the three-dimensional seepage field of tailings dam under steady saturated state was simulated by finite element method (FEM). And the seepage line of saturated - unsaturated seepage field in the tailings dam was simulated and predicted by numerical analysis method when the embankment is enduring the flood. Subsequently, the simulated seepage line of saturated - unsaturated seepage field in the tailings dam was verified by the survey result. Results show that it is feasible to describe the saturated seepage and saturated - unsaturated seepage by means of Darcy law and Richards Equation respectively and it is effective to simulate the three-dimensional seepage field of tailings dam under steady saturated state by using the finite element software Midas GTS. Results also show that the simulated seepage line of saturated - unsaturated seepage field in the tailings dam agree with the survey result.
