摘　　要：本文详细阐述利用全站仪同步进行平面导线测量和三角高程测量的具体实施方法,此方法只需进行一次仪器架设,即可同时进行平面导线测量和三角高程测量相关数据的观测、记录与储存,后平差解算出各个控制点平面坐标和高程,显著提高了作业效率。通过现场实际应用,证明该方法能够满足一般隧道控制网一级导线和四等水准测量的精度要求,能简便快捷完成隧道洞内导线点测量或复核,为类似工程测量提供了借鉴经验。This article elaborates on the specific implementation method of using total station to synchronize plane traverse measurement and triangulation elevation measurement.This method only requires one instrument installation,and can simultaneously observe,record,and store data related to plane traverse measurement and triangulation elevation measurement.After adjustment,the plane coordinates and elevations of each control point can be calculated,significantly improving operational efficiency.Through on-site practical application,it has been proven that this method can meet the accuracy requirements of general tunnel control network's first level traverse and fourth level surveying,and can easily and quickly complete the measurement or review of traverse points inside the tunnel,providing reference experience for similar engineering surveying.
