摘　　要：碾压混凝土试件与混凝土试件一样也存在着尺寸效应。笔者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受剪的细观损伤断裂,并重点对抗剪强度尺寸效应进行了研究。There is the size effect in roller compacted concrete specimen as in concrete specimen. The random aggregate model is used to simulate the structure of the roller compacted concrete. The extension of cracks and the mechanic properties of the roller compacted concrete in shear test are simulated by using the finite element method. The size effect on shear strength of the roller compacted concrete is studied primarily.
