摘要
高铁测量技术的成熟,城市轨道交通建设行业的迅猛发展,给地铁测量技术的创新带来了新的契机。结合常州地铁1号线铺轨工程实例,详细介绍了CPⅢ测量控制网的布设方法与要求,CPⅢ测量控制网的技术指标以及严密平差后的精度分析。结果表明,通过引入高铁上的CPⅢ测量技术来指导城市轨道交通的铺轨工程,能够很好地保证铺轨的精度以及轨道的平顺性和舒适性,对城市轨道交通测量技术的发展具有重要意义。
High speed rail measurement technology and the rapid development of urban rail transit construction industry has brought new opportunities to subway measurement technology.This study has introduced the layout method and requirement,technical indicator and accuracy analysis after rigorous adjustment of CPⅢmeasurement control network combined with Changzhou Metro Line 1 rail laying project.The results show that:CPⅢcontrol network measurement used in urban rail transit laying project can ensure the accuracy of track laying,and the smooth and comfort of track which has great significance to the development of urban rail transit measurement technology.
