摘　　要：波形钢腹板PC组合箱梁桥用波形的钢腹板取代混凝土腹板,是一种新型的钢与混凝土组合结构。该结构有效减小了恒载内力,提高了预应力效率,简化了施工步骤,近年来得到了国内外学者们的广泛关注。针对国内波形钢腹板箱梁桥力学性能、剪力连接件、体外预应力转向块及工程应用等方面的研究进展进行综述。认为我国此类桥梁的理论与试验研究尚不够完善,应加大对波纹钢腹板PC组合箱梁桥的推广和研究深度,并开展工程应用技术研究,形成相应技术标准,指导和推动该类桥型在我国的研究工作和工程应用。The PC composite box-girder bridge,which was used composite steel web instead of concrete web,is a new type of composite steel-concrete structure. In recent years,for it reduced the internal force of dead load effectively,improved the efficiency of the prestressed and simplified the construction procedure,these bridges have been concerned widely by scholars at home and abroad. In this paper,the domestic research results were summarized including mechanical properties,shear connectors,external pre-stressed steering blocks and engineering application of the corrugated steel webs PC composite box girder bridge. It is pointed out that,the theoretical research and experimental research about this kind of bridge in China is not perfect enough,the promotion and depth of research should be increase in the future,application technology research combined with engineering example,should be developed to form corresponding technical standards,in order to guide and improve the research and engineering application of this kind of bridges in our country.
