城市轨道交通调线调坡设计思考

Reflection on Urban Rail Transit Line and Slope Adjustment Design

调线调坡设计工作承上解决土建结构的施工误差,启下为铺轨及设备安装提供良好的条件,是轨道交通铺轨前的最后一道工序。经过系统的调整线路中线和坡度,能使列车运行于良好的三维空间。结合石家庄地铁3号线调线调坡设计经验,总结调线调坡设计原则、调线调坡过程及注意事项,剖析具体方法技巧及实际案例,为工程顺利通车提供良好条件。

The work of line and slope adjustment design is to treat the construction error of civil structure and provide good conditions for track laying and equipment installation.This work is the last process before rail transit track laying,by systematically adjusting the centerline and slope of the line,it ensures the train running in a well-formed three-dimensional space.Combined with the design experience of Shijiazhuang Metro Line 3,the design principles,process and precautions of line and slope adjustment are summarized,and the specific methods,skills and actual cases are analyzed.Issues that require special attention in the design is tracked backwards and proposed,providing good conditions for the smooth opening of the project.
