摘　　要：通过力学性能试验,研究了钢纤维体积掺量和长径比对层布式钢纤维混凝土力学性能影响,对比了层布式钢纤维混凝土与素混凝土和钢纤维混凝土的力学性能,结果表明层布式钢纤维混凝土改善了混凝土的力学性能,提高了混凝土的延性和弯曲韧性。The effect of length-diameter ratio and volumatric fraction of steel fiber on mechanical properties of layer steel fiber reinforced concrete were experimentally studied, and the mechanical properties of layer steel fiber reinforced concrete with normal concrete and steel fiber reinforced concrete were contrasted. The results show that layer steel fiber reinforced concrete improves the mechanical properties, enhances the ductility and toughness of concrete.
