摘　　要：在5%、10%、15%、20%橡胶掺量的橡胶混凝土中外掺1.0%体积率的钢纤维,通过立方体劈裂抗拉试验、棱柱体抗折试验,研究了钢纤维橡胶混凝土的力学性能。实验结果表明:橡胶混凝土立方体劈裂抗拉强度和棱柱体抗折强度随橡胶颗粒掺量的增加而明显下降,掺入钢纤维后的钢纤维橡胶混凝土劈裂抗拉强度先降低后提高,棱柱体抗折强度均明显提高,韧性均显著提高。The properties of steel fiber with volume fraction of 1.0% modified the rubber concrete with 5%, 10%, 15%, 20% four different dosage were tested and analyzed, through cub plitting tensile test and prismoid flexural test. Test results show that rubber concrete cube splitting tensile strength and prismoid flexural strength reduced obviously along with increasing rubber; the addition of steel fiber first improved the cube splitting tensile strength and then reduced; the prismoid flexural strength of rubber concrete modified by steel fiber was improved obviously, the toughness was also significantly improved.
