摘　　要：针对高速磁浮交通工程轨道安装测控的精度要求,设计了一段长度约为350 m的实验用的磁浮轨道安装测控高程控制网(CFIII),并在实验网中分别使用电子水准仪进行一等水准测量和激光跟踪仪进行三角高程间接高差测量,以实验研究分别用这2种仪器及其对应的测量方法建立CFIII高程控制网的精度及其可行性。通过对实测数据的处理与分析,认为采用现行DS05级电子水准仪的一等水准测量和采用激光跟踪仪的间接高差三角高程测量,均能够达到高速磁浮轨道安装测控高程控制网相邻点高差中误差小于0.25 mm和高程中误差小于0.5 mm的精度要求。Aiming at the accuracy requirements of the track installation measurement and control of the high speed maglev transportation project,a section of the maglev track installation measurement and control elevation control network(CFIII) with a length of about 350 m for the experiment was designed.In the experimental network,the electronic level was used for the first-order leveling measurement and laser tracker is used for trigonometric leveling indirect height difference measurement and experimentally studies the accuracy and feasibility of using these two instruments and their corresponding measurement methods to establish the CFIII elevation control network.Through the processing and analysis of the measured data,it is considered that the first-order leveling measurement with the current DS05 electronic level and the trigonometric leveling indirect height difference measurement with the laser tracker can meet the accuracy requirements of the high speed maglev track installation measurement and control elevation control network,which the height difference mean square error of the adjacent points is less than 0.25 mm and the elevation mean square error is less than 0.5 mm.
