通过对碾压混凝土楔入劈拉试件断裂试验结果进行分析研究,得到了碾压混凝土的断裂韧度的尺寸效应规律。将碾压混凝土断裂韧度试验结果与已有的普通混凝土断裂韧度尺寸效应公式结合,通过对几种模型计算结果的分析比较,确定了碾压混凝土断裂韧度尺寸效应所适用的公式。
Size effect rule of fracture toughness of RCC was gotten on the analysis of fracture test results of RCC wedge-split tenside method specimens.Combining the fracture test results of RCC and the existed size effect formula for fracture toughness of common concrete,suitable for-mula for size effect formula for fracture toughness of RCC was confirmed on the comparing of computation results of the models.
