The Seepage Control from Ash Lagoon and the Application of Three Dimensional Mathematical Model

The seepage control is of great importance to the steadiness of the coal ash Lagoon in the thermal power plant. Some drainage patterns of the ash-retention dam are expounded and the development of their design and research is pointed out. The Galerkin method of the weighted residues and the three-dimensional isoparametric element are applied for modelling the seepage field of the ash Lagoon.
