摘　　要：采用落锤试验仪对含有不同掺量和长度的聚乙烯醇、聚丙烯纤维混凝土进行冲击试验,得到了不同配合比材料的位移-时间、拟合力-时间图像。通过对图像的分析得出聚乙烯醇、聚丙烯纤维的掺入大大提高了混凝土的抗冲击能力,同时,研究了纤维的不同掺量、长度、种类以及相互作用效果对提高试块抗冲击性能的影响。It uses the drop hammer test instrument to conduct impact test on the concrete which contain different dosage and length of polyvinyl alcohol and polypropylene fiber and conclude the images of the displacement-time and force-time.From these images we can conclude that the incorporation of polyvinyl alcohol and polypropylene fiber could improve the ability of concrete impact.And find the influences on improving the impact resistance of concrete of different dosage, length, kinds of the fiber and their repercussion effect.

关 键 词：聚乙烯醇纤维 聚丙烯纤维 抗冲击能力
