| 摘 要： | 针对目前在碾压混凝土的断裂性能研究中对内设非穿透矩形裂缝的应力强度因子的计算，普遍采用的方法是将它简单地近似成椭圆形裂缝的形式进行计算的的特点，本文通过对非穿透矩形预留缝试件进行试验分析，对内设非穿透矩形裂缝的应力强度因子的计算公式进行了一定的修正，得到了更好的结果。

| Abstract: | At the present an approximately simple elliptic slot way to make a calculation on the study of fracture performance of roller compacted concrete is often adopted. This kind of calculation is referred to as the stress intensity factor of non-penetrative rectangular slot inside. Through the analysis of testing non-penetrative rectangular preset-slot pecimen, some modifications of the calculation formula about stress intensity factor of non-penetrative rectangular slot inside are made, with much better result obtained. |

| Keywords: | roller compacted concrete preset slot factor of stress intensity |
