| 摘 要： | 为了探讨不同切口对混凝土断裂参数的影响,本文采用两种形式的插板(一种为本文提出的尖细裂纹,顶端仅厚0.16mm;另一种为通常采用的、顶端为30°角)预制混凝土三点弯曲试样的裂纹,对照试验表明尖细裂纹较尖裂纹能获得更为实际的结果.

| Abstract: | In order to investigate the effect of different notches on fracture parameters of concrete, two types of inserting sheets are used to prefabricate the cracks of a three point bending sample. Experimental results show that the fracture parameters are different for different shapes of notch. The difference between K1 and KIs is less than 10% and that between J1 and JIs is greater than 20%. |
