| 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. |
