摘　　要：传统轨道几何状态测量仪在我国高速铁路建设及维护中广泛使用,采用停停走走测量模式,其工法成熟、测量精度高,能够根据轨道几何状态给出相应的调整/动道方案,以便指导轨道调整与维护。全站仪与惯导组合型轨道几何状态测量仪采用连续移动式测量模式,测量效率约为传统轨道几何状态测量仪的15倍。文章主要分析同一设备在相同测量环境下,其由惯导零偏决定的,测量精度与设站距离之间的关系。探索不同阶段轨道精测应用场景下功效分析,在满足施工需求的前提下,为形成更加精准高效的施工方案提供实测分析支撑。The traditional track geometry measuring instrument is widely used in the construction and maintenance of high-speed railway in our country.The stop-and-go measurement mode is adopted,which has mature construction method and high measurement accuracy,and can give the corresponding adjustment/moving track scheme according to the track geometry state,so as to guide track adjustment and maintenance.The combined total station and inertial navigation track geometry measuring instrument adopts the continuous mobile measurement mode,and the measuring efficiency is about 15 times higher than that of the traditional track geometry measuring instrument.This paper mainly analyzes the relationship between the measurement accuracy and the distance of the station,which is determined by the zero deviation of inertial navigation of the same equipment in the same measurement environment.The purpose of this paper is to explore the efficacy analysis under the application scenarios of track precision measurement in different stages,and to provide practical analysis support for the formation of a more accurate and efficient construction scheme on the premise of meeting the construction requirements.
