摘要：对近年来国内外有关混凝土断裂能尺寸效应的研究成果进行了总结与讨论，介绍了混凝土断裂能的试验方法，并针对三点弯曲梁法和楔入劈拉法获得的数据分别进行了分析，讨论了试件高度、宽度、缝高比、跨高比、韧带高度、韧带面积对混凝土断裂能的影响。此外，针对现有研究中存在的不足，提出了下一步研究的方向。 Abstract: The experimental results on the size factors on the fracture energy of concrete in recent years are summarized and discussed. The concrete fracture energy test methods are introduced, and the data obtained by the three-point bending beam method and the wedge splitting method are analyzed respectively. The different influencing factors, such as specimen height, width, seam-to-height ratio, span-to-height ratio, ligament height, ligament area on the fracture energy of concrete are discussed through the data obtained by the three-point bending test and wedge splitting test. In addition, based on the problems in the existing research, the future research direction is proposed.
