摘　　要：对比研究了高强改性聚酯(FC)纤维、聚乙烯醇(PVA)纤维、耐碱玻璃(AR)纤维的掺量(1.0、1.2、1.4 kg/m^(3))对机场道面混凝土抗冻、抗冲击和抗裂性能的影响,并采用TOPSIS综合评价法优选出了最佳的纤维种类和掺量。结果表明:与空白组相比,掺纤维混凝土的抗冻、抗冲击和抗裂性能均有所提高;随着纤维掺量从1.0 kg/m^(3)增至1.4 kg/m^(3),试件的相对动弹性模量、破坏冲击次数比和裂缝降低系数均增大,质量损失率和裂缝总面积均减小;与AR、PVA纤维相比,掺加1.4 kg/m^(3)的FC纤维对混凝土耐久性能的提升效果最好。The effects of the contents(1.0,1.2,1.4 kg/m^(3))of high-strength modified polyester(FC)fiber,polyvinyl alcohol(PVA)fiber,and alkali-resistant glass(AR)fiber on the frost resistance,impact resistance,and cracking resistance of the airport pavement concrete were comparatively investigated,and the optimum fiber type and content were selected by using the TOPSIS comprehensive evaluation method.The results show that compared with the blank group,the frost resistance,impact resistance,and cracking resistance of fiber reinforced concrete are improved.As the fiber content increases from 1.0 kg/m^(3)to 1.4 kg/m^(3),the relative dynamic elastic modulus,the ratio of the number of damaging impacts and the crack reduction coefficient of the specimens increase,and the rate of mass loss and the total area of cracks reduce.Addition of 1.4 kg/m^(3)of FC fiber show the best improvement in concrete durability compared to AR fiber and PVA fiber.
