土石坝沥青混凝土心墙应力状态计算分析

Calculation and Analysis on Stress State of Rockfill Dam Asphalt Concrete Core-wall

摘要: 构建了土石坝的材料本构模型和接触本构模型，采用有限元法分析了某工程沥青混凝土心墙坝的应力状态和变形情况，探讨了不同心墙材料参数、心墙底部与基座之间连接方式对心墙应力状态的影响。

Abstract: The material constitutive model and contact constitutive model of rockfill dam are constructed.The stress state and deformation of asphalt concrete core-wall of a project are analyzed by finite element method. The influences of different core-wall material parameters and the connection mode of the core-wall bottom and the foundation bed on the stress state are discussed.
