摘要
本文根据环行铁道试验基地试验线路的改造，以及准高速试验中轨道状态管理，提出了在准高速铁路既有线改造的困难地段建议使用的欠超高值、最小缓和曲线长度和轨道状态管理值；同时指出，轨道状态安全目标值仍然需要研究确定。
In view of track upgrading in the Loop Track Test Base and track state man-agement in quasi-high-speed testing,the paper proposes the values of deficient supereleva-tion,minimal length Of transition curve and track state management index for use on operat-ing lines where upgrading of the line for quasi-high-speed operation is difficult.At the sametime,the paper aiso points out that the safe track state management target values remain tobe defined through further research work.
