摘要
混凝土结构断裂破坏的尺寸效应现象是八十年代初兴起的热点问题．本文在前人研究成果的基础上，对混凝土断裂尺寸效应律公式进行了探讨，建立了混凝土断裂韧度与试件高度之间的关系，并用试验数据进行了验证．
The study of size effect on fracture failure of concrete has been prevalent since 1980 s. Based on the former Study achievement,this paper discusses the law of size effect on fracture of concrete. The author establishes a formula between the fracture toughness and specimen height,and checks it with test figures.
