基于细观层次混凝土随机骨料模型创建研究

Research on Creating Random Aggregate Model of Concrete Based on the Meso Level

混凝土材料宏观层次的研究无法揭示混凝土内部性能,需从细观层次出发对混凝土进行研究,混凝土细观研究中骨料模型的创建是重要问题之一。基于大量研究学者在混凝土骨料模型创建方面的研究,总结了混凝土骨料模型创建中骨料形状选择、颗粒数计算、有效骨料生成、入侵准则和投放流程等,并且提出在这方面有待进一步解决的问题。

The macro-level of concrete is so difficult to reveal the internal performance that we can research on it from the micro-level. Creating aggregate model is one of the most important problems in concrete micro-level. Based on a large number of researchers in creating concrete aggregate model, the concrete aggregate model created in the ag- gregate shape, particle count, effective aggregate generation, intrusion rule and delivery process and other issues, are summarized, and puts forward the problems which is need to solve in this area.
