摘　　要：近年来,在桥梁工程领域中,钢箱梁、钢混组合梁的应用不断扩大。但钢混组合梁需要解决的问题也相对比较多,混凝土收缩徐变对钢梁的影响就是其中之一。论文对目前常见的中小跨度简支钢混组合梁桥的收缩徐变影响进行研究,以期对设计施工提供一些建议与启发。The application of steel box girder and steel-concrete composite beam has been more and more widely used in recent years in bridge engineering field. However, there are still many problems to be solved for steel-concrete composite beams, such as shrinkage and creep.In this paper, the influence of shrinkage and creep for the composite beam bridge with small and medium-span simple-supported steel composite is studied.

关 键 词：钢混组合梁桥 收缩徐变 有效模量法 长期弹模比
