摘　　要：采用多种本构模型分别对300 m级高心墙堆石坝进行三维有限元计算,分析了本构模型、心墙和坝壳的弹性模量对坝体应力变形及拱效应的影响。结果表明,坝体变形及拱效应规律相近且符合一般规律,具有较高的参考价值。Various constitutive models are used to three-dimensional finite element calculation for core earth-rockfill dam with 300 meter height.The influence of constitutive model,elastic modulus of core and shell on arching effect,stress and deformation of dam body are studied.The results indicate that the arching effect and deformation of dam body is close and accord with regular rules,which has good value for engineering project.
