摘要:
针对现有的接触轨不平顺检测不能有效地利用接触轨检测数据对接触轨线路质量进行评价分析提出了接触轨质量指数(CRQI)及其评价方法,对接触轨不平顺分区段进行管理。利用接触轨检测车在广州地铁 4 号线金洲站-黄村站上行区间的检测数据,分别统计其 CRQI,以及 CRQI 中方向不平顺和高低不平顺的频数分布和累计分布,计算方向不平顺和高低不平顺在 CRQI 中的权重,并分别探讨 CRQI,以 及 CRQI 中方向不平顺和高低不平顺管理值。
Abstracts:
In view of the irregular detection of the existing contact rail which can not effectively use the contact rail test data to evaluate the quality of the contact rail road,a conductor rail quality index(CRQI)and its evaluation method are presented for the section management of the conductor rail irregularities. By the detection data of uplink interval from Jinzhou Station to Huangcun Station on Guangzhou metro Line 4 by the conductor rail inspection van,the CRQI,the frequency and accumulation distribution of horizontal and vertical irregularities in CRQI are calculated separately. The weight coefficient of each kind of irregularity in the proportion of CRQI is computed to explore the management value of CRQI and each irregularity in CRQI respectively.
