摘要
研究目的:在铁路网络的快速完善中,随着不同速度目标值的新建铁路引入既有的枢纽或地区,接轨站方案的优化并配合疏解区桥遂工程设置将至关重要。在山区受桥遂工程的限制,在发达地区受城市规划、公路交通、城市建筑、疏解线多的限制及车站本身场坪限制等增加了接轨站设计难度。接轨站设计在满足运营、工程可行的前提条件下,又能与区间疏解区配合、节省土地资源、节省工程投资,正是站场设计追求、探索的最终目标。研究方法:站场设计结合不同线路引入接轨站的实际情况,在诸多限制条件下尽量增加站场设计的灵活度,并对设计技巧作一个小结。研究结果:小偏角曲线设置可解决接轨站技术难题。研究结论:根据实际情况合理运用不同类型的小偏角曲线。
Researeh purposes： Since new railway lines aimed for different speed ranges will be connected to the existed stations and regions, the optimization of connecting station＇s project to cooperate well with the junction terminal, bridges and tunnels should be very important. The design of connecting station is becoming quite difficult, restricted by the bridges and tunnels in mountainous areas, the cities＇ layout, highways, buildings, a bunch of untwining lines and the limits of stations site＇s length. On one side the connecting stations＇ design should meet the possibility requirements of operating and constructing, and on the other sides it should can cooperate well with the junction terminal and can save land resource and invest. And this is our final goal in our exploration on railway stations＇ design. Research methods：Based on the conditions that different types of railway lines will be connected to stations, the flexibility in design of railway station should be enhanced, even though there are so many restrictions. There is a conclusion of station design＇s technique in this paper. Research results： The problems of junction station can be resolved by designing some curving tracks with small deflective angle correctly. Research conclusions： We can choose different types of curving tracks with small deflective angle, according to different practical conditions.
