| 曲率變化率超限扣分原因分析及對策(52卷) |
| 英文標題 |
| Analysis on cause of over-limit and score-lost of curvature change rate and its countermeasures |
| 摘要 |
| 簡要介紹我國軌檢車的發(fā)展歷程，以上海鐵路局軌檢車2010年全年軌道動態(tài)檢查資料為基礎，提出了新型軌檢車軌道動態(tài)檢查結果中曲率變化率超限扣分及Ⅱ級超限數(shù)量所占比例均較高的課題。根據(jù)曲率變化率的檢測原理及定義，分析曲率變化率超限產(chǎn)生的原因，指出曲率變化率超限產(chǎn)生地點的線型特征及曲率變化率同曲率、正矢、緩和曲線長度之間的相互關系，并以此為依據(jù)分別有針對性地提出減少曲率變化率超限的對策。 |
