摘　　要：以摩洛哥布里格里格河谷斜拉桥工程为背景,介绍了混凝土边主梁与钢横梁组成的结合梁这种新颖的主梁设计,总结了这种主梁的技术特点,与混凝土主梁,以及钢主梁与混凝土桥面板的结合梁相比,这种主梁具有自重较轻、施工方便快捷、造价经济的优点,在桥面较宽的斜拉桥主梁型式选择时,经济上具有较强的竞争优势。Based on cable-stayed bridge over Bouregreg River in Morocco,the paper introduced a new composite main girder design,which connected side main concrete beam with steel cross-beams and summarized its technical features.This kind of main girder have the advantages of being lighter,easi-ly constructed and low cost.This type of composite main girder become more competitive for cable-stayed bridge with wide deck.
