摘　　要：研究了聚丙烯纤维网混凝土的动力学性能。研究结果表明聚丙烯纤维网对提高混凝土抗折强度有显著作用,并可降低压折比,尤为突出的是其弯曲疲劳性能和冲击韧性大幅提高。This paper is special in dynamics performance of reticulate polypropylene fiber concrete. Relevant test and analysis show that the reticulate polypropylene fiber can not only effectively enhances flexural strength and decreases the ratio of compressive strength to flexural strength , but also obviously improves bending fatigue property and impact toughness.

关 键 词：聚丙烯纤维网 弯曲疲劳性能 冲击韧性 压折比
