首先提出高速磁浮轨道(梁)安装测控平面控制网的精度要求,然后建立了小范围的CFⅢ平面控制测量实验网,在实验网中分别进行了基于高精度智能型全站仪和激光跟踪仪的观测实验,并对观测数据进行了处理与分析,以验证用这2种仪器及其对应的测量方法建立高速磁浮轨道安装测控平面控制网的精度及其可行性。实验结果表明,利用激光跟踪仪进行高速磁浮轨道(梁)安装测控平面控制网测量是可行的,且能够满足平差后方向改正数≤±1.5″、距离改正数≤±1 mm、相邻点的相对点位中误差≤±0.5 mm的精度要求。

This paper first puts forward the accuracy requirements of the measurement and control horizontal control network for the installation of high-speed maglev track(beam),and then establishes a small-scale CFⅢhorizontal control measurement experimental network.In the experimental network,the observation experiments based on high-precision intelligent total station and laser tracker are carried out respectively,and the observation data are processed and analyzed to verify the accuracy and feasibility of using these two instruments and their corresponding measurement methods to establish a high-speed maglev track installation measurement and control horizontal control network.The experimental results show that it is feasible to use the laser tracker to measure the horizontal control network of high-speed maglev track(beam)installation measurement and control,and can meet the accuracy requirements of directional correction number less and equal than 1.5″,distance correction number less and equal than±1 mm and relative point position mean square error of adjacent points less and equal than±0.5 mm.
