AbstractThe magnitudes of the hydrodynamic pressures at the dam-fluid interface depend on the amount of energy transmitted to the fluid by the vibration of the reservoir boundaries. Although the reservoir topology can have a considerable impact on the amount of generated energy, it has still not been adequately addressed. This paper treats an arch dam-fluid interaction considering a compound wave field of compressive and dilatational waves in a reservoir with a complex topology. A truncation surface was located at a distance beyond which the simulated wave field has only negligible effects.
Summary(Plain Language Summary, not published)
The magnitudes of the hydrodynamic pressures at the dam-fluid interface depend on the amount of energy transmitted to the fluid by the vibration of the reservoir boundaries. This paper focuses on the generation of hydrodynamic forces in reservoir with a complex geometry and the dynamic dam response. It represents the first step in treating the vulnerability of concrete arch and gravity dams to seismic forces.
