摘　　要： 首先探讨了水工混凝土存在的影响其耐久性的开裂、冻融、碳化、磨损等问题,然后结合国内外关于聚丙烯纤维混凝土的试验研究成果,分析了聚丙烯纤维对水工混凝土抗裂、抗渗、抗冻、抗冲击、抗疲劳、抗冲耐磨和抗碳化等性能的改善作用,分析结果表明,聚丙烯纤维可有效提高混凝土的耐久性能. In this article, the factors on durability such as crack, thaw-freeze, carbonization, fray were discussed firstly. Then, the improvements of polypropylene fibre on the property of anti-cracking, anti-seeping, anti-frost, anti-impact, anti-fatigue, anti-carbonization were analyzed, combined with the experimental results in the world. The results indicated that polypropylene fibre could increase the durability of concrete evidently.
