混凝土断裂力学性能研究综述

Review of research on fracture mechanics of concrete

在工程结构中,包含了一大类力学性能的准脆性材料,混凝土作为一种典型的非均质准脆性材料,在工程界有很大的研究背景。以至于国内外大量学者针对像混凝土这类准脆性材料提出了一系列研究方法。通过梳理国内外学者在混凝土断裂性能方面的试验研究,总结归纳了混凝土断裂参数的测试方法、力学模型及影响因素等。在此基础上,对混凝土断裂发展规律的研究前景进行了展望,希望为以后此类问题的研究奠定基础。

The engineering structure contains a large class of quasi-brittle materials with mechanical properties.As a typical non-homogeneous,quasi-brittle material,concrete has a great research background in engineering.So many scholars at home and abroad have proposed a series of research methods for quasi-brittle materials such as concrete.By combing the domestic and foreign scholars in the experimental study of concrete fracture performance,summed up the concrete fracture parameter testing methods,mechanical models and influencing factors.On this basis,the research prospects of the fracture development law of concrete are prospected,and it is hoped to lay a foundation for future research on such issues.
