Analysis on Seismic Response Characteristics of a Face Rockfill Dam across an Extra Wide River Valley

Abstract:

No relevant high earth face rockfill dams built across a river valley with a width-to-depth ratio of more than 8.0 is reported both at home and abroad. In this paper, non-linear finite elements method is adopted to analyze the seismic response of a 139m high CFRD proposed across a river valley with a width-to-depth ratio of 9.5, and dynamic response conditions such as dam’s absolute acceleration, dynamic displacement and dynamic stress etc., are highlighted Analysis results show that under existing design conditions, due to great river valley’s width-to-depth ratio, dam’s seismic response under an earthquake action of 8 Richter Scale is not intense, but an evident whipping effect occurs at the crest, it is necessary to take corresponding anti-seismic engineering measures.
