摘　　要：纤维混凝土的抗冲击性能是指在反复冲击荷载作用下,复合材料吸收动能的能力。通过对耐碱玻璃纤维混凝土、聚丙烯纤维混凝土、钢筋混凝土以及普通混凝土的抗冲击性能进行对比试验研究。试验结果表明:加入柔性纤维明显改善混凝土的抗冲击性能,有利于提高混凝土结构的耐久性。Impact resistance performance of the fiber reinforced concrete means the capacity of composite materials absorbing the kinetic energy under repeated impact load. Contrastive experiments of the impact resistance performance are carried out between alkali-resistant glass fiber reinforced concrete, polypropylene fiber reinforced concrete, reinforced concrete and ordinary concrete. The results of the experiment draw the conclusion that adding flexible fiber into the concrete can obviously improve the impact resistance of concrete and it is also advantageous to enhance the durability of the concrete structure.
