空中自行车快速道跨路段施工技术

Construction Technology of Cross Section in the Air Lane of Bicycle

空中自行车道设计考虑缓解交通压力及绿色出行,在原有城市道路基础上进行修建。自行车道与现有城市道路网存在交通路口穿插问题,其中从中央带到道路边的路段为典型跨路段,跨路段钢箱梁由于钢构件横跨道路,且柱间间距较大,钢箱梁分段体量大,施工难度高。以厦门云顶路自行车快速道示范段工程为依托,通过三维建模模拟分析及现场实际施工应用,总结适用于空中自行车道跨路段的施工技术。

The constraction of the air lane of bicycle is based on the urban road exzisted,designed for relieving pressure of trsportation and green travel.There is a problem that the air lane of bicycle is interspersed with the existing urban road network,and the crossroads with lots of vehicle is really a problem.The road that from central zone to roadside is a typical cross section,which has a difficulty in costracting.The distance between one column to another is large and the weight of steer box girder is huge,which cause such a difficulty.Relying on the building of The demonstration project of air lane of bicycle on Yunding Road Xiamen,the article concludes a new method used for cross section during the constraction of air lane of bicycle by analysis of 3 d modeling and application in practice constraction.
