城市轨道交通曲线钢轨调边可行性分析

Feasibility Analysis on Exchanging Upper and Lower Rails on Transit Curved Track

小半径曲线段钢轨侧磨是城市轨道交通不可避免的问题,曲线钢轨调边使用是延长钢轨使用寿命的有效方式,从曲线钢轨调边的安全性、耐久性、焊接方式、调边方式以及施工组织等几个方面,对城市轨道交通实施钢轨调边的可行性进行分析,以期该项技术能够广泛应用于城市轨道交通曲线钢轨侧磨的治理。

Concerning several aspects of rails on curved track from the safety, durability, welding and exchanging rails methods and construction organization etc. the feasibility of exchanging rails on the transit line is analyzed. It is expected that the technology can be widely used in transit maintenance to deal with curved rail side wear problems.
