【摘要】：现代有轨电车作为低碳环保、安全可靠、美观舒适的绿色交通方式,兼有地铁、公交的诸多优点。现代有轨电车一般敷设在市政道路路中或路侧,由此会带来交通组织与信号控制、横断面布设、平面线形协调、纵断面标高协调、路基路面过渡等诸多问题。基于此,以现代有轨电车敷设在沥青路面道路中央为例,对二者交通组织、平纵横协调、路基路面衔接过渡等技术问题进行分析,并提出协调措施:通过对区域路网、路段及交叉口、沿线单位出入口、行人过街交通组织的优化,确保行车安全;在市政道路靠近有轨电车一侧设置30 cm宽平石,并预留0.5 m路缘带,有轨电车适当预留限界外空间,以确保二者限界不重叠;通过设置立缘石和平石,协调有轨电车专有路权段的超高和工后沉降差异问题;交叉口混行路段,通过轨道左线和右线与剩余部分交叉口分别形成路口进行竖向设计,以实现高程协调;同时设置过渡段,协调有轨电车与市政道路混行段路基的差异沉降。
[Abstract]:As a low-carbon environmental protection, safe and reliable, beautiful and comfortable green transportation mode, modern tram has many advantages of subway and public transportation. The modern tram is usually laid in the road or side of the municipal road, which will bring many problems such as traffic organization and signal control, cross-section layout, plane alignment, vertical section elevation coordination, roadbed and pavement transition and so on. Based on this, taking modern tram laying in the center of asphalt pavement as an example, this paper analyzes the technical problems such as traffic organization, horizontal and horizontal coordination, subgrade and pavement transition and so on, and puts forward some coordination measures: through the regional road network, Road sections and intersections, entrances and exits of units along the route, optimization of pedestrian traffic organization across the street to ensure traffic safety; 30 cm wide flat stone on the municipal road near the side of the tram, with a 0.5 m road belt reserved, Suitably reserve outer space for trams to ensure that the two boundaries do not overlap; coordinate the issue of super-high and post-construction settlement of tram exclusive right sections by setting stone and peace stone on the vertical edge; intersections with mixed sections, Through the intersection between the left and right rail lines and the remaining part of the intersection, the vertical design is carried out to achieve height coordination, and at the same time, the transitional section is set to coordinate the differential settlement of the roadbed in the mixed section of the tram and the municipal road.
