摘　　要：利用反演预测模型,结合混凝土面板堆石坝原型观测资料,对大坝填筑料的邓肯E-B模型参数进行反演分析,并用反演所得的坝体材料参数及其实际填筑过程进行有限元计算,得到坝体及面板的变形值;利用模型对水库蓄水三年后的变形值进行计算;根据实际监测结果与计算值进行对比,证明了有限元计算结果的合理性。Back analysis of the Duncan EB model’s parameters of material building in dam is carried out by using inversion prediction model and prototype observation data of the concrete face rockfill dam.Deformation values of dam and face plate are obtained by FEM analysis using the parameters of dam material,considering its actual filling process.Then the model is used to predict deformation values after three years of reservoir impounding.According to comparisons between monitoring results and predicted values,the rationality of the finite element calculation results and the effect on construction and operation management are both analyzed.
