摘　　要：通过有限元计算研究次堆石区材料参数对300 m级超高面板堆石坝应力变形的影响,比较分析表明:次堆石区材料参数对高面板堆石坝的应力变形有较大影响,初步确定主次堆石模量比宜控制在1.5∶1以内,以期为300 m级超高面板堆石坝的建设提供参考。This paper studies the impact of the material parameters in hypo-rockfill zone on the stress and deformation of 300 m concrete face rockfill dam through finite element analysis.the results of comparative analysis show that the material parameters in hypo-rockfill zone play an important part in the stress and deformation of high concrete face rockfill dams,and it is preliminarily determined that the reasonable modulus ratio between main and hypo-rockfill zones should not be larger than 1.5∶1,which serves as a reference for high concrete face rockfill dam constructions.
