钢纤维增强混凝土(SFRC)承载能力强,在建筑、交通、水利等方面应用前景广阔.近年来对SFRC的研究主要集中在增强机理、力学性能、腐蚀防护以及数值模拟等方面.SFRC的力学性能优于普通混凝土,能有效防止脆性破坏的产生;SFRC腐蚀防护的研究未涉及到相关腐蚀机理分析,主要侧重对腐蚀行为的观察;SFRC的数值模拟贴近实际情况,已经逐步实现了宏观与细观的结合.然而,对钢混杂纤维增强混凝土的研究尚处于初步阶段,需在增强机理、本构关系以及耐久性研究等方面深入进行,为钢混杂纤维增强混凝土的实际工程应用提供理论与技术支持.综合论述了目前SFRC各个方面的研究进展,展望了钢混杂纤维增强混凝土的应用前景.
Steel fiber reinforced concrete ( SFRC) has broad application in architecture,transportation and irri-gation works due to its more excellent bearing capacity. In recent years,the research of SFRC mainly focused on strengthening mechanism,mechanics behavior,corrosion resistance and numerical simulation. Brittle failure can be effectively prevented because of the better mechanical properties of SFRC. The research of SFRC primary focuses on the corrosion behavior and not related to the corrosion mechanism. The numerical simulation of SFRC is close to the reality and has gradually realized the macroscopic and microscopic combination. However,the research of steel hybrid fiber reinforced concrete is still at a preliminary stage and need deeply study on enhancement mechanism, constitutive relation and durability research. Thus,the applications of steel hybrid fiber reinforced concrete can be supported in theory and technology. The study and progress of SFRC at present were summed up,and the trends of SFRC were predicted.
