摘　　要：为探讨玄武岩纤维增强混凝土在水利工程中的抗冲磨及耐久性表现,研究了不同纤维掺量(0%、0.5%、1.0%、1.5%)对混凝土抗压强度、抗拉强度、耐腐蚀性能、抗裂性和疲劳性能的影响。结果表明,玄武岩纤维的加入显著提高了混凝土的力学性能和耐久性,其中1.0%~1.5%的纤维掺量效果较好。在不同腐蚀环境下,纤维增强混凝土的质量损失明显减少,耐腐蚀性能显著提升。此外,纤维的加入有效延缓了裂缝的产生,显著提高了混凝土的抗疲劳性能。玄武岩纤维增强混凝土的使用能够有效提升工程结构的使用寿命和安全性。To investigate the abrasion resistance and durability of basalt fiber-reinforced concrete(BFRC)in hydraulic engineering,the effects of different fiber contents(0%,0.5%,1.0%,and 1.5%)on the compressive strength,tensile strength,corrosion resistance,crack resistance,and fatigue performance of concrete were studied.The experimental results indicated that the addition of basalt fibers significantly enhanced both the mechanical properties and durability of the concrete,with the optimal fiber content found to be between 1.0%and 1.5%.In various corrosive environments,the mass loss of fiber-reinforced concrete was notably reduced,demonstrating improved corrosion resistance.Moreover,the inclusion of basalt fibers effectively delayed crack initiation and substantially improved the concrete's fatigue performance.The application of BFRC in hydraulic engineering and other harsh environments holds promising prospects,as it can significantly extend the service life and safety of engineering structures.
