中文摘要：
通过试验，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及断裂性能的影响，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及断裂性能，结果表明：层布式钢纤维混凝土改善了混凝土的力学性能，提高了混凝土的断裂韧度和断裂能．
英文摘要：
The effect of length - diameter ratio and volumetric fraction of steel fiber on mechanical properties and fracture performance of Layer Steel Fiber Reinforced Concrete have been experimentally studied. Compared the mechanical properties and fracture performance of Layer Steel Fiber Reinforced Concrete with Normal Concrete and Steel Fiber Reinforced Concrete,the results show that Layer Steel Fiber Reinforced Concrete improves the mechanical properties, enhances the fracture toughness and fracture energy of concrete.
