摘　　要：采用等体积置换法,将橡胶粉分别按10%、20%、30%、40%、50%取代细集料配制橡胶混凝土,并通过不同掺量的纤维对其进行增强,分析并评价了橡胶混凝土的力学性能、耐磨性能以及抗冲击性能。试验结果表明:纤维增强橡胶混凝土的抗压强度较基准混凝土有大幅度降低,抗折强度以及劈裂强度明显增大;随着纤维和橡胶粉的掺入,混凝土的耐磨性能和抗冲击韧性均有所提高,且随着纤维掺量的增加而增大;当纤维掺量0.9kg/m3左右,橡胶粉体积掺量不超过40%时,混凝土性能最为优异。The kind of concrete with diiierent content ot tiber Is prepared using the volume dmplacement methocl to replace fine aggregate by the rubber powder of 10%, 20%, 30%, ＇;0%, 50%. The mechanical properties, wear resistance and impact resistance of the fiber reinforced rubber concrete are analyzed and evaluated. The results show that the com- pressive strength of fiber reinforced rubber concrete significantly reduce compare with normal concrete, while the flexural strength and splitting strength of the fiber reinforced rubber concrete significantly increase; adding fiber and rubber pow- der can the enhance wear resistance and impact toughness of the concrete, and these properties increase with the increas- ing content of fiber; When the fiber content is about 0.gkg/m3, the rubber content is less than 40% of fine aggregate（vol- ume content）, the concrete performance is the best.
