轨道交通工程中跨江水准测量关键技术的应用

Application of Key Technology of River Crossing Leveling in Rail Transit Engineering

控制测量是轨道交通建设过程中的重要技术环节和隧道顺利贯通的重要保证,大多数城市轨道交通都存在跨河跨江的情况,因此跨江水准测量必定是控制测量中必不可少的一个环节。以上海市轨道交通10号线二期跨黄浦江水准测量为例,介绍一种简便的跨江水准测量方法,此方法简便可靠,能够满足轨道交通平高控制精度要求和轨道交通施工的要求。

In rail transit construction,control survey is a key technical process and an important basis for tunnel linking up.Most urban rail transit needs to cross river,thus the leveling of which becomes essential in control survey.Taking the second-phase leveling(across the Huangpu River)of Shanghai Rail Transit Line 10 as an example,this paper introduces a simple and reliable cross-riverleveling method,which can meetthe accuracy and construction requirements.
