轨道交通新建线路与既有线路的衔接测量探讨

Discussion on the Junction Measurement Between the New Line and the Existing Line of Railway Transportation

当新建线路与既有线路交叉或顺接时,必然存在结构和轨道的衔接问题。以郑州城郊铁路一期工程为背景,从衔接测量的步骤、作业方法及实际案例几个方面出发,对轨道交通新建线路与既有线衔接时测量工作需要注意的问题进行总结,对今后轨道交通新、老线路衔接测量具有参考和指导意义。

When the new line is crossed with the existing line or is connected with the existing one, that will eventually produce some junction issues of structure and railway. Taking the first stage construction of Zbengzhou suburban railway as the background, paper summarizes the key points needing to pay attention to when measuring thejtmction between the new line and the existing line, from the aspects of the steps of junction measurement, the method of operation and the practical cases, in orderto provide reference to the futurejnnction survey of the new line and old line.
