- The objectives of the study are: (1) to develop an effective procedure for analyzing the response of concrete arch dams to earthquake ground motion, including the effects of dam-foundation rock interaction with inertia and damping of the foundation rock considered, dam-water interaction, and reservoir boundary absorption; (2) to identify the limitations of the 'standard' analysis procedure which considers the flexibility of the foundation rock but ignores its inertia and damping - material and radiation - effects; and (3) to study the effects of dam-foundation rock interaction in the presence of dam-water interaction and reservoir boundary absorption on the response of the dam, leading to better understanding of these effects. This investigation emphasizes the effects of dam-foundation rock interaction compared to dam-water interaction which have already been studied extensively.
