高铁CPⅢ技术在地铁铺轨工程中的应用与分析

The Application and Analysis of High-speed Railway CPⅢ Technology in Metro Rail Laying

高铁测量技术的成熟与地铁建设的兴起,给地铁测量技术的发展与创新带来了契机。本文首先对高铁CPⅢ网和传统地铁铺轨方法进行了分析,介绍利用CPⅢ技术建立地铁轨道控制网的方法,轨道控制网测量的技术指标和利用CPⅢ网精调轨道的流程;并结合宁波地铁1号线实例,利用CPⅢ网和采用传统控制基标测量方法调整轨道的数据进行了轨道的平顺性分析比较,最后得出几点有益的结论。

The maturity of high-speed railway survey technology and the rise of metro construction, have brought opportunity to metro survey technology development and innovation. Based on the comparison between traditional method of track-laying and CPIII technology,the paper introduces the method of building metro control network with CPIII technology. The technologic index of rail control network survey,and the process to accurately adjusting rail with CPIII network, taking Ningbo metro line 1 as an example, the rail＇s regularity analysis and comparison are making between the use of CPIII network and traditional control standard measurement method which to adiust the railnzv, and some helpful conclusions are making in the end.
