中低速磁浮与公路合建方案研究

Study on Joint Construction Scheme of Medium and Low Speed Maglev and Highway

中低速磁浮为绿色、环保的新型交通方式,可以沿公路采用高架方式敷设。当两者线路走向一致时,根据公路条件、轨道交通设站情况等因素,可采用合建方案,以达到节省用地,降低工程投资的目的。本文针对不同外部条件,研究四种不同的合建方案,确定不同合建结构的适用范围。研究结果表明:采用合建方案,两项目共用一个征地红线,减少了工程用地;可以减少一次对城市的分割,整体景观效果相对较好;共用一个桥墩基础,减少了部分共用结构,总体投资较省;同步规划、同步设计、同步施工,减少施工过程中的干扰。研究结论对于邻近公路建设中低速磁浮等轨道交通方案研究具有一定的参考价值,可为未来城市综合交通建设提供新思路。

Medium and low speed maglev is a green and environment-friendly new mode of transportation,which can be laid in an elevated way along the highway.When the two lines are in the same direction,the joint construction scheme can be adopted according to the highway conditions,the setting of rail transit stations and other factors,so as to save land and reduce project investment.According to different external conditions,this paper studies four different joint construction schemes and determines the application scope of different joint construction structures.The results show that:the joint construction scheme is adopted,and the two projects share one land acquisition red line,reducing the project land;it can reduce one-time segmentation of the city,and the overall landscape effect is relatively good;sharing one pier foundation reduces some common structures and saves overall investment;synchronous planning,design and construction can reduce the interference in the construction process.The research conclusion has a certain reference value for the research of rail transit schemes such as medium and low-speed maglev in the construction of adjacent roads,and provides new ideas for the construction of urban comprehensive transportation in the future.
