纤维混凝土通过引入不同类型纤维，可有效改善混凝土脆性破坏特征与断裂后力学性能，是实现混凝土高性能化与功能化的重要途径.本文系统综述了金属纤维、合成纤维、无机纤维及天然纤维混凝土的研究进展，重点综述了不同纤维对混凝土抗压、抗拉、抗弯及抗冲击性能的增强效果及其适用特征.在此基础上，从微观阻裂与宏观增韧两个层面，深入分析纤维-基体界面粘结特性、纤维几何参数及分布状态对裂缝演化与能量耗散行为的影响机理.综合现有研究可知，纤维增强效果受纤维类型、掺量、界面性质及服役环境等多因素耦合作用制约.最后，针对当前纤维混凝土在机理认知与工程应用中存在的问题，展望了界面调控、多尺度机理建模、复合纤维协同增强及绿色低碳纤维混凝土的发展方向.
Abstract：By incorporating various types of fibers, fiber-reinforced concrete can effectively improve the brittle failure behavior and post-cracking mechanical performance of concrete, serving as a key strategy for achieving high-performance concrete. This paper systematically reviews the research progress on metal, synthetic, inorganic, and natural fiber-reinforced concrete, with a focus on the enhancing effects of different fibers on compressive, tensile, flexural, and impact resistance properties,as well as their applicability characteristics. From the perspectives of micro-crack resistance and macro-toughening, the influence mechanisms of fiber-matrix interfacial bonding properties, fiber geometry, and dispersion state on crack evolution and energy dissipation behavior are elucidated.Current research indicates that the reinforcing efficiency of fibers is governed by the coupling effects of multiple factors, including fiber type, content, interfacial characteristics, and service environment.Finally, addressing existing challenges in the mechanistic understanding and engineering application of fiber-reinforced concrete, future directions are outlined, such as interface tailoring, multi-scale mechanistic modeling, synergistic reinforcement using hybrid fibers, and the development of green and low-carbon fiber-reinforced concrete materials.
