京九线160km/h区段既有曲线状态的控制

Control on existing cursive status of 160/km/h section on Jing Jiu Line

针对京九线既有曲线技术标准低，提速160km/h 后动态曲线水平加速度出分多，曲线动态检查质量不高的情况，对提速线路曲线水平加速度产生的机理进行理论分析，并制订了提速线路曲线静态控制标准和养护措施，为保证提速列车安全、平稳运行提供了保证。

Facing low level of technical standard on Jing-Jiu existing cursive track,after speed raising to 160/km/h,acceleration on cursive track level is notsatisfied and the dynamic detecting quality on cursive track is not high,it analyzes theoretically on the generation of acceleration on speed raisingcursive track level and works out the static control standard of speed raising cursive track and its maintenance measures,which ensures speed raisingtrain safety and stable running.
