摘　　要：利用直径为φ74mm的变截面SHPB装置对钢纤维混凝土进行冲击压缩试验,其中钢纤维长为6mm、长径比为40的超短钢纤维,体积掺量分别为0%、3%、6%。试验得到了不同应变率下的全过程应力应变曲线。试验结果表明:随着钢纤维含量和应变率的提高,材料的强度增加。The impact compressive experiments of steel fiber reinforced concrete were conducted by Ф74 mm SHPB.The steel fiber is a kind of super-short, super-thin steel fiber with 6mm long and its length/diameter is 40, the volumn content of the fiber is 0%, 3%, 6% respectively.The experiments gained the stress-strain curves and the experimental results showed that the strengths of concrete were increasing when the content of fiber and the strain rate improve.
