摘　　要：以长方体叠合梁为研究对象;通过纤维增强应变水泥基复合材料-钢筋混凝土叠合梁三点抗弯试验;从裂缝发展情况、抗弯能力以及变形能力等方面展开;讨论纤维性质和养护龄期对叠合梁产生的影响;并与普通钢筋混凝土叠合梁进行比较分析。发现纤维增强应变水泥基复合材料-钢筋混凝土叠合梁较之普通钢筋混凝土叠合梁有着更好的承载能力与抗弯性能;可以将限裂与分散混凝土裂缝的作用发挥出来。纤维增强应变水泥基复合材料代替混凝土保护层技术能够推广并应用于结构加固修复作业中。展形态的影响。Taking cuboid superimposed beams as the research object;through the three-point bending test of fiber-reinforced strain cement-based composites and reinforced concrete superimposed beams;the influences of fiber properties and curing age on the crack development;bending capacity and deformation capacity of superimposed beams are studied;and compared with ordinary reinforced concrete superimposed beams.It is found that fiber-reinforced strain cement-based composite beams with reinforced concrete have better bearing capacity and flexural performance than ordinary reinforced concrete composite beams;and can play the role of crack limiting and dispersing concrete cracks.Therefore;the technology of fiber-reinforced strain cement-based composite replacing concrete protective layer can be popularized and applied in structural reinforcement and repair operations.
