摘　　要：智能型全站仪结合边角后方交会原理在高速铁路测量工作中得到广泛应用,其在CPⅢ高精度铺轨控制网的基础上进行自由重叠设站的精度能满足高铁测量的精度要求。在板式无碴轨道底板放样和轨道板安装时,可以根据仪器误差参数计算得出每个测站进行放样时误差不超限的最远放样距离,供测量人员参考。Robotic total station combined with the principle of linear-angular resection has widely used in the high-speed rail measurements,based on the CP Ⅲ high-precision track-laying control network,the precision of the free overlap station can completely satisfy the requirements of high-speed measurement accuracy. In the slab ballastless track plate lofting and orbital plate installation,calculate the farthest lofting distance according to the instrument error parameters on each station under the lofting error do not overrun,to provide the reference for measuring personnel.
