Seepage Design Charts for Embedded Dams Resting on Heterogeneous Media
The quantity of seepage under the foundation of most hydraulic structures is of great significance to dam engineers and designers since it plays an essential part in the dam design and safety. Acquiring seepage estimates under dams may not be a straightforward task especially if the underlaying stratum exhibits heterogeneous and/or anisotropic properties. Since exact or analytical solutions for this seepage problem are non-attainable, researchers have developed several techniques in order to approximate the seepage quantity. Flownets and the method of fragments are two techniques that have long been used with limited success in furnishing seepage under hydraulic structures. Several numerical models that provide seepage estimates have been developed by making use of the finite difference and the finite element methods, or other numerical modeling tools. In this research study, an efficient and accurate method for obtaining seepage estimates under hydraulic structures was developed. The finite element method was successfully implemented for providing seepage and exit gradient estimates under embedded dams with single sheet piles underlaid by heterogeneous media. The data obtained from the numerical model was compiled and plotted to form different sets of design charts. These charts could be used efficiently for obtaining seepage and exit gradient estimates under the aforementioned structures. The results obtained from the finite element model were compared and verified against existing relevant mathematical approximation and other techniques. Designers and practitioners in the field would benefit from these charts because of their simple yet accurate estimates.
