Analytical solutions of two-dimensional turbulent seepage in rock-fill dams
2007 (English)Conference paper (Refereed)
Turbulent seepage in porous media, often in rock-fill dams, represents a classical topic. Easy estimation of the seepage flow characteristics facilitates the slope stability analysis of a dam. In this paper, we revisit the analytical approach in two dimensions for solving turbulent seeping flow in homogenous isotropic rock-fill dams lying on an impervious foundation. The derivation of its analytical solution is simplified. The usefulness of the analytical formulations is improved in a sense that explicit expressions of the seepage point location in the downstream slope and the phreatic surface are worked out. The seeping discharge can be easily computed, although its accuracy relies on a good knowledge of the turbulent permeability of a dam. The analytical approach is useful when an approximate answer is needed.
