Dam–Water–Foundation Interaction Effects in Earthquake Response
This chapter presents the responses of Pine Flat Dam to Taft ground motion under different assumptions for the foundation and for the reservoir and a range of properties of the wave‐absorptive reservoir bottom. Based on these results, it identifies the effects of dam–water interaction, reservoir–bottom absorption, and dam–foundation interaction on the earthquake response of concrete gravity dams. The earthquake response of Pine Flat dam is increased by dam–water interaction and decreased by reservoir bottom absorption with the magnitude of these effects depending on the condition of foundation, rigid or flexible, and on the component of ground motion, horizontal or vertical. In particular, both dam–water interaction and reservoir bottom absorption have a profound effect on the dam response to vertical ground motion irrespective of the foundation condition, but relatively less, although still very significant, effect on the dam response to horizontal ground motion with the magnitude of the effect decreasing further if dam–foundation interaction is included.
