摘　　要：结合常导高速磁浮交通施工和轨排精调的精度要求,反推常导高速磁浮交通工程控制测量精度要求。以上海磁浮、长沙中低速磁浮的建设实践,以及多年高速铁路工程测量经验,对常导高速磁浮交通工程测量体系进行探讨,提出适合常导高速磁浮交通工程勘测、施工、运营维护测量体系;根据常导高速磁浮交通工程车体类型、工程结构、设计及施工各阶段需求,提出平面控制网分三级布设、高程控制网一级布设的测量方案;按照不同土工结构设计控制点的布点、埋设、观测方法。磁浮测量体系应跟随磁浮新技术、新需求以及测量新技术不断改进,发展成为适应工程需要、经济合理的方法。Considering the accuracy requirements of the construction and the track panel precising adjustment of the highspeed EMS Maglev,the survey control accuracy will be deduced.Based on the construction practice of Shanghai Maglev,Changsha medium and low-speed maglev and the high-speed railway engineering survey experience over the years,the survey system of high-speed EMS maglev engineering is fully discussed,which should be suitable for the measurement,construction,operation and maintenance.The survey scheme of three-level horizontal and one-level elevation control network is proposed to meet the requirements of vehicle type,structure design and all the construction stages.The planing,burying and observe methods of the control points are designed according to the different forms of geotechnical structures.The maglev measurement system should be developed following the new technology,new requirements and the new measuring technology,to accommodate the engineering needs and be cost effective.
