摘要
轨道梁施工线型与设计线型最大程度匹配,将提高线路的平顺性,增加乘坐列车的舒适性。本文采用了一种轨道梁活动对中器及测量标志,改进了轨道梁线型高精度测量方法,提高了轨道梁线型测量精度,分析了施工线型成果与设计线型的关系,将对类似轨道梁线型高精度测量工程提供经验参考。
The maximum matching between the construction line type and the design line type of the track beam will improve the smoothness of the line and increase the comfort of the train.This paper use a kind of track beam movable centering device and measurement mark,improves the high-precision linear measurement method of track beam,improves the linear measurement accuracy of track beam,analyzes the relationship between construction linear results and design linear,and provides experience reference for similar high-precision linear measurement engineering of track beam.
