摘要
Through critical state sand model cooperating with the concept of state-dependent dilatancy,a group of fully coupled finite element analyses of the response of a central core rock-fill Dam are presented for the study of the seismic performance.The numerical analysis is on the SUMDES2D platform.The dam was built directly on bedrock to earthquakes of different intensities.The dynamic response of the dam under earthquake intensity was analyzed.The calculation results show that,the bigger the earthquake intensity is,the larger the permanent deformation and local deformation would occur in the dam.
