摘要
本文用三点弯曲试样测定了钢纤维高强混凝土的断裂韧度ＫＩＣ，试验研究表明：钢纤维高强混凝土的断裂韧度明显大于普通钢纤维混凝土的断裂韧度。另外，还试验研究了裂缝深度变化对断裂韧度的影响．
An experimental investigation of the fracture toughness in high strength fiber-reinforced concrete was concducted by using three point bend specimens,The fracture toughness KIC of high strength fiber -reinforced concrete is greater than that of the common reinforced concrete.In addition,The influence of crack depth on frature toughness is discussed.
