Abstract: As the benefits of simple structure, economic construction and less effect of weather, asphalt concrete core wall dam gets more and more attention. In this paper, the nonlinear Duncan-Chang E-B model is used to establish the constitutive relation between the asphalt concrete core wall and the dam. Considering the contact between asphalt concrete core wall and the dam, two-dimensional finite element method (FEM) is adopted in calculation of the stress-strain of the asphalt concrete core wall. Theoretical calculation on the maximum and minimum stress and deformation of the dam provides a reference for the structural calculation of the dam.

Key words: Guanwen reservoir, asphalt concrete, core wall dam, stress-strain

摘要: 沥青混凝土心墙坝具有结构简单、建造经济、受气候条件影响小等优点,越来越受到人们的关注。采用Duncan-Chang非线性E-B模型模拟大坝堆石体及沥青混凝土心墙的本构关系,考虑沥青混凝土心墙与坝体堆石料间的接触,采用二维有限元方法对某沥青混凝土心墙坝应力变形进行计算分析。从理论上计算大坝的最大、最小应力及变形量,为大坝的结构计算提供参考。
