摘要
主要介绍天津地铁7号线局部线路方案比选的过程。在城市开发尚未成熟区域,线路走向应结合周边区域控规来选择;在城市开发较为成熟区域,线路走向应结合周边建筑物来选择。针对方案中所遇到的各种控制点,采取相应的措施,例如在区间隧道采取重叠方案设计、个别曲线采用小半径曲线等,为其他城市的地铁选线提供借鉴。
This paper mainly introduces the process of comparison and selection of the partial line alignment scheme of Tianjin metro line7.In the areas where urban development is not yet available,the line alignment should take into consideration of the development plans of the surrounding area.In the more developed urban area,the track alignment should take into consideration of the surrounding buildings.Corresponding solutions are put forward for various ruling points encountered in the scheme,for example,section tunnels overlapping scheme design and sharp curves in some areas etc,so as to provide references for other city metro alignment selection.
