北京燕房线线路方案设计中重、难点问题的研究及应对措施

Research on Key and Major Challenges in Alignment Design of Beijing Yanfang Line

随着我国城镇化的推进,市郊新城不断涌现,轨道交通也逐步由中心城向市域范围拓展,市郊线成为线网中重要组成部分北京燕房线是服务燕房地区、支持燕化产业基地发展的远郊高架线、如何做好与市区线网的衔接?如何使线路走向与城市规划相吻合,从而有效支持市郊新城的发展?如何处理好与规划道路、重大管线、高压走廊、城市景观等控制因素的关系?这些是线路方案研究中的重、难点通过对解决方案的探讨,分享市郊高架线方案设计的思路。

With the advancement of urbanization in China,new cities are constantly emerging in suburb,and rail transit is gradually extending from the central city to the outskirt area.Suburban lines have become important parts in the rail transit network.Beijing Yanfang Rail Transit Line is a suburban viaduct serving Yanfang area and supporting the development of Yanshan Petrochemical Industrial Base.In the alignment design,the key and major challenges are how to link with the urban network,how to deal with the relationship with the control factors such as planned roads,major pipelines,high-voltage corridors and urban landscape.The solutions are analyzed and studied,and the ideas in the design of suburban viaduct are shared.
