地铁调线调坡设计方法探讨

Discussion on Design Methods for Metro Line Track Adjustment

城市地铁工程土建完工后,为消除施工误差、满足限界要求,需对区间隧道、桥梁及车站等土建工程进行限界检核,并需对线路原有设计进行调线调坡。文章就线路平纵断面、曲线超高等调线调坡设计方法以及设备尺寸和安装位置调整等进行探讨。

After completion of metro civil engineering works, in order to eliminate the construction error, meet the requirements of clearance, check and inspection on clearance of civil engineering works such as tunnels, bridges and stations and route in the original design including route alignment and adjusting gradient. The paper discusses the design method of track profile and alignment, the adjustment design method of the curve superelevation, and the adjustment of the dimension and position of the components.
