摘要：Elastic modulus,load and unload plastic modulus of generalized plastic P-Z model were improved by considering pressure dependency of dam-filling gravel materials,and experimental data of static and dynamic triaxial tests of the gravels were used to calibrate the improved model＇s parameters.By using this model,a static and dynamic finite element method（FEM） was adopted to analyze a gravel concrete-faced rockfill dam（CFRD） of 200m-grade high.The results show that permanent dam deformation under earthquakes can be directly obtained with the improved generalized plastic model,and that the behaviors of static deformation,dynamic responses and permanent deformation obtained through elastic-plastic analysis are reasonable.Thus consideration of pressure dependency by the improved model is feasible and effective.
