摘　　要：混凝土材料的断裂能是一个最为重要的混凝土非线性断裂力学参数,其大小标志着材料裂纹扩展的难易程度,对分析混凝土结构的性能有重要指导意义。通过几种柔性纤维混凝土(砂浆)试件的断裂能对比试验,研究不同纤维对混凝土(砂浆)试件断裂性能的影响,得出了一些有益的结论,为桥梁设计、施工和加固提供参考。As a most important mechanical parameter of concrete nonlinear fracture and with its magnitude marking the degrees of difficulty of expansion of material cracks, the fracture energy of concrete material presents important instruction for analyzing the property ot~ concrete structure. By compared test for a few specimens of flexible fiber concrete （motor）, this paper investigates effects of different fibers on fracture property of concrete （motor） specimens and draws some instructive conclusions as to provide reference for design, construction and reinforcement of bridge.
