采用大变形有限元方法,分析了水泥混凝土路面嵌缝料在拉伸和剪切作用下的结构应力,总结了嵌缝料最大拉伸应力和最大剪切应力、嵌缝料宽深比、拉伸应变和剪切应变,以及嵌缝料有效模量和泊松比之间的关系,给出了它们的计算回归公式。
The large deformation finite element method is used to analyze the structural stress of cement concrete pavement under tension and shearing. The maximum tensile stress and maximum shear stress of the caulk are summarized. Elongation strain and shear strain, as well as the relationship between effective modulus and Poisson’s ratio of caulking material, and their calculation regression formulas are given.
