Abstract

The seismic design of earthfill and rockfill dams routinely relies on methods of analysis which adopt simplifying assumptions regarding the dynamic response of the reservoir, while the dynamic interaction of the fluid and solid phases within the dam body is also typically ignored. In this paper, a simple numerical approach for the efficient simulation of hydrodynamic pressures in finite element analysis is presented and then used to assess the impact of hydrodynamic pressures on the seismic response of dams. The importance of both hydrodynamic pressures and of hydro-mechanical coupling is then discussed within the context of two well-documented case studies, of an earthfill and a rockfill dam, comparing the numerical predictions against field measurements.
