摘    要:混凝土力学特性是大坝、海洋平台等工程结构抗震设计及仿真分析的前提条件之一, 也是目前研究的薄弱环节. 混凝土是一种典型的非均质材料, 其宏观力学特性由细观组成来决定. 本文总结了目前研究混凝土宏观力学特性的细观力学分析方法, 细观有限元法及理论分析法; 阐述了界面过渡区(ITZ)对混凝土性能的影响, 简单介绍了混凝土界面过渡区问题的研究现状; 介绍了作者提出的混凝土宏观力学性能研究的细观单元等效化分析方法. 最后对其未来发展的一些方向和有待进一步研究的问题作了总结.

关 键 词:混凝土  细观力学  界面过渡区  力学特性

Abstract:Mechanical properties of concrete are one of the prerequisites in seismic design and simulation analysis of engineering structures,such as dam and ocean platform.While the research on concrete mechanical performance is the weak link in the current study.As known,concrete is a typical heterogeneous material,and the macro mechanical properties are determined by meso ingredients.The meso-mechanical methods for studying the macro-mechanical properties of concrete currently,that is,the meso-mechanical finite ele...
Keywords:concrete  meso mechanics  interfacial transition zone  mechanical properties
