碾压混凝土单轴抗压强度尺寸效应的数值模拟

Numerical Simulation of Size Effect of the Uniaxial Compression Strength of Rolled Compacted Concrete

碾压混凝土与混凝土一样也存在着尺寸效应。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压的细观损伤断裂,并重点对单轴抗压强度尺寸效应进行了研究。

There is size effect to rolled compacted concrete as concrete, the random aggregate model was used to simulate the structure of rolled compacted concrete. The extension of cracks and the mechanic properties of rolled compacted concrete in uniaxial compression test were simulated using finite method. The size effect on uniaxial compression strength of rolled compacted concrete was studied primarily.
