摘要
综述了混凝土类材料宏观力学参数估算中细观夹杂理论的解析方法和细观数值试验的数值方法的研究现状,重点介绍了界面连接完好的混凝土类材料有效模量估算的一些分析方法,并对细观夹杂理论和细观数值试验方法的发展趋势进行了展望,认为今后的研究热点将是针对混凝土中界面连接不完好和基体材料非线性这两个根本特征下的有效强度估算以及体现混凝土细观特征的宏观本构关系的建立.
A review was made on the current research on estimation of macroscopic mechanical parameters of concrete from two aspects, i.e. the analytic method based on mesoscopic inclusion theory and the meso-numerical experiments, with emphasis placed on some analytic methods for estimation of effective moduli of concrete materials with perfect interface, and the development trend of the research was prospected. Furthermore, the hotspots in further research were put forward, i.e. the estimation of the effective strength of concrete materials with imperfect interface and nonlinear matrix and the establishment of macro-constitutive relationship with the mesoscopic parameters of concrete.
