摘　　要：介绍了一种新型的组合结构桥梁,其主梁采用波形钢工字梁,桥面系为FRP桥面板,该结构充分利用波形钢工字梁优越的抗剪承弯能力,以及FRP材料抗拉、抗疲劳、抗腐蚀能力强等优点,实现了主桥结构的装配化施工。结合大广高速深州至大名段分离式立交桥工程,详细阐述了波形钢腹板-FRP桥面板组合桥梁的施工方案。这种新型桥梁结构的应用对于推进桥梁创新意义重大。A new composite bridge, which uses corrugated I-shaped beam as its main beam and FRP slab for the deck, was introduced. This kind of structure combines the shear strength of the corrugated I-shaped beam and advantages of FRP materials including great tensile strength, anti- fatigue, anti-corrosion performance. In terms of the separated interchange project of Shenzhou- Daming section of Daqing-Guangzhou expressway, construction scheme for the new composite bridge was expounded. The application of bridge comprised of corrugated steel web and FRP slab is expected to prompt the innovation of bridges.
