摘要
CPⅢ控制网测量技术在高铁中已成功运用,地铁采用此技术将提高铺轨精度和效率,是地铁铺轨施工、运营养护的发展趋势。文章简要介绍CPⅢ控制网测量技术及在高铁中的应用,并结合地铁的特点、地铁部分线段的试验结果,提出适用于地铁轨道测量的CPⅢ控制网测量建议。
CPⅢ control network measurement technique has been successfully used in high-speed railway ,and it is a development trend for metro to use this technology which will improve the accuracy and efficiency of metro track laying and maintenance. The paper briefly describes the CPⅢ control network measurement technique and its application in high-speed railways, takes into consideration of characteristics of metro, test results of some metro sections, and puts forward some applicable proposals on CPⅢ control network for measurement of metro track.
