介绍秦沈客运专线可动心轨辙叉单开道岔结构不平顺的分布特征,指出其作为一种初始不平顺会严重影响后期不平顺的产生与发展,并用广深线实测结果进行说明。分析秦沈客运专线岔区实测不平顺分布特点,指出大号码道岔在铺设时容易出现的问题,为控制初始不平顺提供依据。
This paper introduces the distribution features of track irregularity on movable-point frog single turnout on the Qinhuangdao-Shenyang dedicated passenger line and points out that the initial irregularity will have serious impact over the creation anddevelopment of the later irregularity by using the actual data collected from the Guangzhou-Shenzhen line.
