OPTIMUM LOCATION OF DRAINS IN CONCRETE DAMS

An analytical solution based on seepage theory is presented to determine the average uplift pressure across the section of a gravity dam having a system of equally spaced drains of uniform diameter. The optimal location of the drains for the minimum uplift has also been obtained. It was found that the average uplift pressure varies linearly from full head at the upstream face to a certain value at the drain location and again linearly to the downstream head at the dam toe. These and other study findings are discussed.
