| 摘 要： | 结合横琴口岸莲花大桥改造工程设计实例，介绍了针对复杂环境下的小半径桥梁设计与施工方案比选过程，提出了采用组合梁、局部上跨临时保留匝道时则采用钢箱梁的综合结构方案以及合适的施工方案，对于同类型小半径桥梁设计工作具有一定的借鉴价值。

| Abstract: | Combined with the design example of Hengqin Port Lianhua Bridge Reconstruction Project, the comparison and selection of the design and construction schemes of the minor-radius bridges in the complex environment are introduced. The integrated structural scheme and the suitable construction scheme of using the composite girder and using the steel box girder when locally spanning the temporarily retained ramps are put forward, which has the certain referring values for the design of the similar minor-radius bridges. |
