交叉口范围道路与有轨电车竖向协同设计研究

Research on Vertical Collaborative Design of Roads&Trams within the Scope of Intersections

道路交叉口范围内竖向设计主要通过纵、横坡的调整,解决相交道路行车舒适、与周边建筑地块标高衔接及道路排水问题。在有轨电车通过的交叉口范围内,由于受到轨道线路标高及钢轨道岔整体制作工艺等限制,对交叉口竖向设计带来更多的控制因素。通过对有轨电车钢轨道岔设置标高和制造要求的分析,以嘉兴市有轨电车的各类复杂交叉口为例进行竖向设计分析,总结不同类型下交叉口范围道路与有轨电车竖向协同设计的典型方法。

The vertical design within the scope of road intersections mainly solves the problems of driving comfort,elevation connection with surrounding buildings,and road drainage by adjusting the longitudinal and transverse slopes.Within the scope of intersections where trams pass through,due to the limitations of the track line elevation and the overall manufacturing process of steel track turnouts,there are more control factors in the vertical design of intersections.Through the analysis of the setting elevation and manufacturing requirements of steel track turnouts for trams,taking various complex intersections of Jiaxing tram as examples for vertical design analysis,it summarizes typical methods for vertical collaborative design of roads and trams within different types of intersections.
