摘要
本文介绍了混凝土细观力学的研究方法,总结了到目前为止在细观层次上对混凝土实验研究和数值模拟的研究成果,详细分析讨论了格构模型、随机骨料模型和随机力学特性模型3种细观力学数值模型的优缺点。目前混凝土细观力学的研究主要集中对细观数值模型的研究,已建立起来的细观数值模型仍待完善,同时尚缺乏系统的各相材料力学特性参数试验测定成果。用细观力学数值模拟取代部分试验任务还要做很多工作。
The authors briefly summarized the analytical methods of concrete micro-mechanics and the current state of studies on experimental investigation and numerical simulation.Emphases were put on the discussion of lattice model,random aggregate model and random property model of concrete micro-mechanics.Their merits and demerits were also indicated.It was shown that studies and investigations were still needed to improve the numerical model of micro-mechanics,constitutive relation and damage evolving model and to conduct systematic tests for determining the model parameters.-
