摘要:

接触轨膨胀接头安装曲线是城市轨道交通工程中指导膨胀接头安装的重要依据，其合理性直接影响线路运营阶段接触轨的正常使用及维护。与地下段接触轨相比，高架段接触轨由于位于高架桥梁上，其伸缩量不仅受轨条自身温度变化的影响，还受到高架桥梁外部因素的影响。通过研究高架段接触轨的锚段伸缩情况，给出了高架段接触轨膨胀接头安装曲线的修正建议，可为工程中高架段接触轨膨胀接头的安装提供参考。

Abstracts:

The installation curve of contact rail expansion joint is an important document to guide the installation of expansion joint in urban rail transit engineering. Its rationality directly affects the normal use and maintenance of contact rail in the operation stage of the line. Compared to the underground contact rail system, the expansion of the elevated contact rail system is not only affected by the temperature change of the rail itself, but also by the external factors of the viaduct. Through research of the expansion and contraction condition of the anchor section of the elevated contact rail system, correction suggestions are given for the installation curve of the contact rail expansion joint in the elevated section, which can provide reference for the installation of the contact rail expansion joint in the elevated section of the project.
