Application of Finite Element Analysis in Seepage and Anti-slip Stability of Tailings Pond

In the preliminary design of a proposed tailings pond, one-time dam construction is adopted, and the dam type is roller compacted earth rock dam. In order to evaluate the rationality of the design scheme and the safety of the tailings pond, the seepage and anti-slip stability of the tailings pond were calculated by the finite element method. The results show that the seepage control system adopted by the tailings dam can well meet the seepage control requirements. The HDPE geomembrane on the upstream side of the dam has played a good seepage interception effect, and the distribution law of the infiltration line in the reservoir is reasonable. At the same time, the drainage system designed for the downstream has played a good seepage effect. Under the three conditions of normal storage level, maximum flood level and earthquake, the sliding stability of the downstream slope of tailings dam meets the specification requirements, proving that the design scheme is reasonable and feasible.
