摘　　要：CPⅢ控制网作为高速铁路建设过程中所布设的第三级测量控制网,在我国高铁领域得到了广泛应用。城市轨道交通与高铁在施工工艺、轨道形式上有相似之处,其测量技术同样有许多相似之处,城市轨道交通建设中引用CPⅢ方法大大提高了铺轨精度和效率,提高列车运行的稳定性,同时也使城市轨道交通测量技术和铺轨手段发生变化,是轨道施工、运营维护阶段测量技术的一大革新。本文以高铁CPⅢ技术为基础,结合实际需要,对CPⅢ控制网用于中低速磁浮线路轨道精调进行了实际应用探讨,实践证明,该方法能够很好地满足本工程轨道铺设要求,但也存在需要进一步探讨的问题。As a third-level measurement control network laid in the course of high-speed railway construction,CPⅢcontrol network has been widely used in the field of high-speed rail in China.Urban rail transit and high-speed rail have similarities in construction techniques and rail forms,and their measurement techniques have many similarities also.The introduction of this method in urban rail transit construction greatly improved the accuracy and efficiency of rail laying and improve the stability of train running.At the same time,it will also make these changes in measurement technology and rail paving,which is a great technical improvement of measurement technology in stage of rail construction and Operation and maintenance.Based on CPⅢtechnology of the high-speed rail and combined with the actual work,this paper verifies that using the CPⅢcontrol network to carry out medium-low speed maglev track precision adjustment,the practice showed that the method can meet the requirements of track laying,but further researchesare needed for some remained problems.
