摘　　要：进行了3种标号混凝土在不同钢纤维掺入形式下的力学性能试验,对比研究了混杂钢纤维掺入和单一钢纤维掺入对混凝土力学性能的增强作用。给出混杂钢纤维掺入混凝土在工程应用上的使用建议。In the paper, several adopted widely definitions and calculation methods of evaluation to SFRC toughness factor were summarized, various toughness factor calculation expressions＇ physics meaning were deduced and analyzed. Though the contrast and analyse of results of SFRC standard member in bending flexibility test, many calculation methods＇ merits and drawbacks and scope of application were pointed out, performance suggestions in practice engineering were offered.
