【Abstract】 In this paper, the boundary condition of general absorptive reservoir bottom is derived, and the method for analyzing hydrodynamic pressures on rigid structures with the general conditions is presented. In the studies, the reservoir bottom is idealized as laminated elastic media and the water as compressible but non-viscous liquid.The point collocation method is used to investigate the water pressures on dams due to horizontal harmonic ground motions. Based on the results from typical examples, some important characteristics of water pressures and water loads on rigid dams with general absorptive reservoir bottom are illustrated.In this paper, the boundary condition of general absorptive reservoir bottom is derived, and the method for analyzing hydrodynamic pressures on rigid structures with the general conditions is presented.
