城市快速路跨线桥设计探讨

Discussion on the design of city expressway flyover

以太原市北中环—和平路跨线桥设计为例,对两种桥梁结构方案进行了综合对比,采用变截面预应力混凝土箱梁桥,并探讨了桥梁结构的总体设计方法,有助于城市快速路跨线桥设计水平的不断提高。

Taking Taiyuan North Central-Peace Road overpass design as an example, this paper made comprehensive comparison to two kinds ,3f bridge structure schemes, using variable cross-section pre-stressed concrete box girder bridge, and discussed the general design method of bridge structure, contribute to the continues improvement of city express way overpass design standards.
