| 曲率变化率超限扣分原因分析及对策(52卷) |
| 英文标题 |
| Analysis on cause of over-limit and score-lost of curvature change rate and its countermeasures |
| 摘要 |
| 简要介绍我国轨检车的发展历程，以上海铁路局轨检车2010年全年轨道动态检查资料为基础，提出了新型轨检车轨道动态检查结果中曲率变化率超限扣分及Ⅱ级超限数量所占比例均较高的课题。根据曲率变化率的检测原理及定义，分析曲率变化率超限产生的原因，指出曲率变化率超限产生地点的线型特征及曲率变化率同曲率、正矢、缓和曲线长度之间的相互关系，并以此为依据分别有针对性地提出减少曲率变化率超限的对策。 |
