| Abstract | The purpose of this investigation is to determine analytically the uplift pressure and overturning moment on a dam resting on a porous foundation of finite depth. The equations for the uplift pressure and overturning moment were obtained from a mathematical solution of the Laplace equation using methods of conformal transformation. These equations relate the uplift force and overturning moment to the geometry of the structure, depth of the porous media and the upstream and downstream heads of water. The equations for the uplift pressure and overturning moment were obtained in integral form. Numerical results were obtained however by expressing the integral in finite difference form and numerically integrating the equations over the base of the structure. The computations for both uplift force and overturning moment were performed by the IBM 1620 electronic computer. The accuracy of the resulting values were confirmed J by comparing the theoretically determined results with calculations based on pressure distribution obtained from an electric analog model. The form of computed results enabled design curves to be constructed which relate the uplift pressure and overturning moment in dimensionless form with the geometry of the structure, depth of porous media and the upstream and downstream heads. |
