Seismic Response Analysis Method of High Core Rockfill Dam

Abstract

A dynamic constitutive model is suggested based on dynamic triaxial test data of dam materials. Combining with construction of a high core rock-fill dam, several key issues, such as dam seismic response, dam permanent deformation, filter layer anti-liquefaction, dynamic strength of the core wall are analyzed by using 3-D dynamic effective stress analysis method. And some useful conclusions and regularity are obtained in the aspects of seismic response and anti-seismic properties. The analysis method and conclusions could be referred to the analogous engineering.
