前言在混凝土中掺入一定数量的纤维是改善混凝土受力性能的重要措施之一。钢纤维混凝土是纤维混凝土中性能最好的一种,它具有良好的韧性、抗裂性和抗爆炸荷载等性能。六十年代中期以来,受到各国工程界的重视,并成为新的研究课题。从一九七二年起先后在伦敦,伯明翰和渥太华等地召开了纤维增强混凝土的国际会议,大大推动了纤维混凝土的研究和应用。目前,钢纤维混凝土已被应用于机场跑道、公路路面、隧道衬 Introduction The incorporation of a certain amount of fiber into concrete is one of the important measures to improve the mechanical performance of concrete. Steel fiber reinforced concrete is the best one in fiber reinforced concrete. It has good properties such as toughness, crack resistance and explosive load resistance. Since the middle of the 1960s, it has attracted the attention of engineering circles from all countries and has become a new research topic. Since 1972, international conferences on fiber-reinforced concrete have been held in London, Birmingham and Ottawa, which have greatly promoted the research and application of fiber concrete. At present, steel fiber reinforced concrete has been applied to airport runways, highway pavements, tunnel linings
