摘要：The Latin hypercube sampling was used to select the model parameters of rockfill for FEM analysis,the settlements of typical observation points during completion period were computed by FEM,the response surface method was used to establish the mapping relationship between the model parameters and the values of settlement,the model parameters of the rockfill were determined by the inverse analysis based on the values of actual measured settlement,an inverse analysis method based on the response surface method was proposed to determine the generalized plasticity model parameters of rockfill materials.The proposed method was applied to determine the rockfill parameters of Zipingpu CFRD through the monitoring settlements in the construction stage.The seismic response of Zipingpu CFRD during Wenchuan earthquake was simulated by the inverse parameters and the results were compared with the actual seismic damage survey.The results indicated that both the developing process of the vertical displacements of the typical points during the stage of construction period and the permanent deformation of the dam due to the earthquake agreed well with the field measured.
