高速铁路无砟轨道线路动静态检测数据均值差异性研究
Research on Mean Value Difference between Dynamic and Static Inspection Data of High-speed Railway Ballastless Track
摘要
Abstract
As one of the main index for evaluating track irregularities, mean value management can reflect the overall quality status of track section, which is more meaningful for ballastless track of high-speed railway due to its high ride comfort and high stability. Therefore, on the base of the dynamic and static inspection data from Hangzhou-Changsha, Nanjing-Anqing passenger dedicated lines and Hefei-Fuzhou high-speed railway, this paper analyzes the differences of the inspection data from the two kinds of railways. The results show that the differences between dynamic and static inspection data of ballastless track are extremely small, especially those in terms of track alignment and gauge irregularity. Track irregularity status, structural type and initial quality contribute much to the differences. Therefore, track fine adjustment quality should be addressed during the construction of ballastless track, and both dynamic and static management of ballastless track should be enforced during the operation period with reference to the differences of track structures.关键词
