全球定位系统(Global Position System,GPS)技术凭借精准定位、实时监测、数据记录与分析等优势,在贵南高速铁路建设中发挥着关键作用,成为不可缺少的工具.竣工图是高速铁路建设的重要资料.随着现代经济社会的发展,越来越多的高速铁路项目正在建设中,竣工图作为对高速铁路进行验收、运营、维护和改造的可靠依据,在整个工程中起着至关重要的作用.通过对贵南高速铁路(贵州段)竣工图的测量,重点探讨GPS技术在贵南高速铁路竣工测量中GPS的控制网布设、观测及后期数据处理和平差计算等内容.
Application of GPS Technology in the As-Built Survey of Guiyang—Nanning High-Speed Railway
Global Position System(GPS)technology plays a key role in the construction of the Guiyang-Nanning High-Speed Railway by virtue of its advantages of precise positioning,real-time monitoring,data recording and analysis,and improved work efficiency and makes an indispensable tool.As-built drawing is an important data of high-speed railway construction.With the development of modern economy and society,more and more high-speed railway projects are under construction.As-built drawing,as a reliable basis for acceptance,operation,main-tenance and transformation of high-speed railway,plays a vital role in the whole project.Based on the survey of the as-built drawing of the Guiyang-Nanning High-Speed Railway(Guizhou section),this paper focuses on the GPS control network layout,observation,post data processing and adjustment calculation in the as-built survey of the Guiyang-Nanning High-Speed Railway.
