摘要:
本文通过分析不同工况对半径250 m曲线无缝线路临界轨温的影响，合理确定半径250m曲线作业轨温范围及稳定性影响因素。结合现场养护维修过程中遇到的问题和设备整修方法，从钢轨选用及修理、轨枕选用、道床修理等方面提出半径250 m曲线稳定性控制措施。
Abstract:
This paper analyzes the influence of different working conditions on the critical rail temperature of CWR with a radius of 250 m, and reasonably determines the operating rail temperature range and the influencing factors of the stability of the curve with a radius of 250 m. In light of the problems and equipment renovation methods encountered during the field maintenance and repair, the stability control measures of curves with a radius of 250 m are put forward from the aspects of rail selection and repair, sleeper selection, and roadbed repair.
