摘　　要：碾压混凝土的强度关系到碾压混凝土结构的安全。采用随机骨料模型模拟碾压混凝土的细观结构,利用有限元方法数值模拟碾压混凝土试件单轴抗拉的细观损伤断裂,并对其单轴抗拉破坏过程进行了研究。The strength of Rolled Compacted Concrete provides important effect to the safety of Rolled Compacted Concrete construction.The random aggregate model was used to simulate the structure of concrete.The extension of cracks and the mechanic properties of Rolled Compacted Concrete in uniaxial tension test were simulated using finite method.The process on uniaxial tension of Rolled Compacted Concrete was studied.

关 键 词：碾压混凝土 单轴抗拉 数值模拟
