摘要
钢纤维混凝土由于能有效地改善混凝土材料的力学性能,在道路工程中得到了较多的应用。文中对钢纤维混凝土在不同纤维含量、不同试件宽度以及不同初始裂缝深度下的断裂性能进行了试验研究。研究表明钢纤维混凝土的临界应力强度因子KIc和临界J-积分JIc与试件宽度无关,但随着初始裂缝深度的增加而减小。
An experimental analysis of the fracture properties of steel fiber reinforced concrete including critical stress intensity factor（KIc ） and critical J-integral（JIc ） was conducted by using three point bending specimens with varying thickness,notch depths and different fiber volume contents.It was found that KIc and JIc was independent of the thickness of specimen but decreased with increasing notch depth.
