中文摘要：

对国内外学者针对界面过渡区对混凝土力学性能的影响的主要研究成果进行了概述，并对混凝土细观数值模型中有关界面单元的力学性能（厚度、本构关系及破坏准则和随机力学参数等）进行了探讨。通过分析目前试验、理论以及数值分析的成果，指出目前对界面过渡区力学性能的试验研究水平较低，还有待进一步发展。

英文摘要：

The paper summarized the main research results of the influence of interface transition zone to the mechanical properties of concrete of domestic and foreign scholars and discussed the mechanical properties of related interface units （thickness,constitutive relations and failure criteria and stochastic mechanics parameters）of the concrete mesoscopic numerical model. Through the analysis of the present theory and test,the results of numerical analysis and finally it pointed out that the interface mechanics performance test research level was low and still needed further develop-ment.
