摘要
研究钢纤维混凝土中裂缝扩展规律,对钢纤维混凝土应用有重要意义。文章介绍了钢纤维混凝土开裂的过程与特点、阻裂机理、断裂模型,并概述了裂缝扩展表征与测试方法以及钢纤维对裂缝扩展的影响,为钢纤维混凝土应用提供参考。
It is of great significance to study the law of crack propagation in steel fiber reinforced concrete. This paper reviews features and the cracking process, resistance mechanism of cracks, fracture model of steel fiber reinforced concrete, and summarizes the characteristics of the crack propagation, the test method, and the influence factor of steel fiber to cracking propagation, which might have references for the application of the steel fiber reinforced concrete.
