摘　　要：对《钢纤维混凝土结构设计与施工规程》(CECS3 8:92 )作了全面修订,编制成《纤维混凝土结构技术规程》(CECS3 8:2 0 0 4)。新规程增补了合成纤维混凝土的有关设计与施工的内容;钢纤维品种中淘汰了低强圆直型纤维、碳钢熔抽型纤维,新增了高强钢丝切断型、铣削型、剪切异型和低合金钢熔抽型纤维;混凝土的强度等级由CF2 0～CF40扩大到CF80 ,并考虑了钢纤维对中低强度和高强度混凝土增强作用的不同,分别给出了有关材料性能和各项构件设计的影响系数;在隧洞支护与衬砌和工业建筑地面设计中引入了考虑钢纤维混凝土韧性的设计概念;增补了钢纤维增强屋面板、承台、牛腿、深梁、码头铺面、桥面、桥梁结构、水工结构、层布式复合路面等领域有关的设计施工内容。Technical specification for fiber reinforced concrete structures(CECS38:2004) has been publicized and replaced the old specification (CECS38:92). In the new specifications, content of design and construction on synthetic fiber reinforced concrete is added, the round straight steel fiber of low strength and the melt extracted steel fiber with lower containing of carbon are eliminated, high strength fiber cut from steel wire, specially shaped fiber milled from steel ingot or sheared from steel sheet and melt extracted steel fiber with low alloy are recommended. The strength grade of fiber reinforced concrete is extended from 40MPa to 80MPa. To take into account the effects of steel fibers on different strength concrete, different effecting factors are given to estimate performances of the concrete with different strength grade and each computation of elements made of the fiber reinforced concrete. The toughness of fiber reinforced concrete is induced into the design of tunnel liner and industrial floor. The design and construction methods of roof slab, pile cap, corbel, deep beam, pavement of dock and bridge, bridge structures, structures of hydraulic engineering, layered composite pavement,and so on, are added.
