该文以武汉市武青三干道互通式立交为例,着重介绍了立交设计的平、立面布置,桥梁结构设计,立交桥中变宽异形梁及小半径曲线梁的设计方法。该设计不仅降低了工程造价,也为快速施工提供了有利条件。

Taking Wuqing No.3 Highway Interchange in Wuhan City as an example, the article stresses the introduction on the plane and elevation layouts of the interchange, the design of the bridge structure, and the design methods of the widening shaped beam and the small-radius curve beam in the interchange. This design not only reduces the engineering construction cost, but also provides the favorable condition of the high-speed construction.
