Web21 okt. 2004 · Abstract. Hydrodynamic pressures on the vertical upstream face of straight dams during horizontal earthquakes were studied by Westergaad in 1933, and an analytical solution was obtained. Assuming that water is incompressible, an approximation can be made to reduce Westergaad’s mathematical formulation to the Laplace equation. Web( 1952) determined the hydrodynamic pressures experimentally using an electrical analogue. Because of the mathematical difficulties involved in determining exactly the hydrodynamic pressure exerted on an inclined upstream face of a dam by horizontal earthquakes, no analytical solutions are available in the literature.
