九江长江大桥提速后线路问题较为严重,而且一直未能得到有效控制,为研究其爬行规律,通过对桥上长轨伸缩调节器一年的爬行观测数据的分析与研究,从总体上得出了大桥线路爬行的相关规律,主要表现在同一线两钢轨不同步爬行,上行线爬行量大于下行线,总的爬行方向与基本与行车方向一致等,同时还对引起爬行的相关原因进行了分析。 Jiujiang Yangtze River Bridge speed after the more serious line problems, and has not been effectively controlled, in order to study the law of its crawling, long-leg extension bridge on the bridge by one year of creep observation data analysis and study concluded that The law of creeping on the bridge line mainly shows that the two rails on the same line are not synchronized and crawl, the amount of creeping on the upper line is greater than that on the lower line, the general direction of creeping is basically the same as the driving direction, and the related causes of crawling are also analyzed.
