【摘要】 混凝土结构断裂破坏的尺寸效应问题是近几十年来一个十分重要的研究领域．本文分析了混凝土断裂参数产生尺寸效应的原因，讨论了断裂过程区的测试方法，对国内外提出的一些尺寸效应的分析方法进行了评述．在此基础上对混凝土断裂尺寸效应的研究提出了自己的看法更多还原

【Abstract】 Fracture size effects for concrete structures have been a very important field of civil engineering for more than ten years. In the paper the size dependency of some conventional fracture parameters are discussed,some tests on fracture process zone are described, the studies on size effect both in China and abroad are analyzed and reviewed. Some comments are made on the development trends of fracture size effect for concrete structures.更多还原
