上海轨道交通15号线圆形隧道调线调坡设计研究

Research on Line and Slope Adjustment Design of Circular Tunnel of Shanghai Rail Transit Line 15

调线、调坡设计是城市轨道交通线路设计中的重要一环。通过对结构断面进行限界检核,针对侵限地段进行调线、调坡设计,从而减小或消除侵限情况,为将来铺轨、设备安装提供保障。结合上海轨道交通15号线工程实例,介绍了圆形隧道调线、调坡设计的主要流程与方法。

Line and slope adjustment is an important part in the design of urban rail transit lines.By checking the clearance of the structural section,line and slope adjustment is carried out for the section with limit violation,so as to reduce or eliminate the limit violation and to provide guarantee for future track laying and equipment installation.Taking the engineering of Shanghai Rail Transit Line 15 for case study,the main process and method of line and slope adjustment design of circular tunnel are introduced.
