摘　　要：港口工程设计中长引桥结构通常采用大跨度钢桥与预应力混凝土T型梁或空心板梁方案,并得到了大量广泛的应用,设计及施工方案比较成熟可靠。本工程结合桥梁工程的经验,提出了采用后张预应力混凝土带翼小箱梁的结构方案,为长引桥结构设计提供参考。In port engineering design, long bridge approach usually adopted long-span steel bridge being combined with pre-stressed T-shape concrete beam or hollow slab girder, which had been widely applied due to its mature and reliable design and construction plans. Based on bridge engineering experiences, a structural option of small concrete box girder under post-tension pre-stress was put forward, which served as a reference for the design of long bridge approach.
