未来的超高面板堆石坝的设计与施工将以变形控制为核心,面板堆石坝的变形与堆石体的材料密切相关,然而,堆石体的材料是一种典型的非线弹性材料,因此选取能够准确反映堆石体应力和变形关系的本构模型将是解决坝体变形的有效措施之一。在广泛阅读国内外相关文献的基础上,选取在经典弹塑性理论与亚塑性理论中具有一定代表性的沈珠江双屈服面弹塑性模型与Gudehus-Buaer亚塑性模型进行系统的理论分析与对比,为堆石体材料应力应变分析模型的选取提供理论依据。
The design and construction of future ultra-high CFRD will center on deformation control. The deformation of CFRD is closely related to the material of rockfill body. However, the material of rockfill body is a typical nonlinear elastic material Therefore, selecting a constitutive model that can accurately reflect the relationship between stress and deformation of the rockfill will be one of the effective measures to solve the deformation of the dam body. On the basis of extensive reading of relevant literature both at home and abroad, this paper systematically analyzes and contrasts the ShenZhuJiang double yield surface elasto-plastic model and the Gudehus-Buaer sub-plastic model, which are representative in the classic elasto-plastic theory and the sub-plastic theory, It provides a theoretical basis for the selection of stress-strain analysis model of rockfill materials.
