摘要
针对特大区域城市轨道交通首级控制网覆盖面积广、线路长、历经时间久、工作量大等特点,将广州市城市轨道建设作为切入点,结合现有线路以及远景规划,成功解决了特大区域城市轨道交通首级控制网建设的若干重大技术问题。
The characteristics of large regional rail transit control network such as covering a wide area, long lines, long time span, large work intension, which was discussed in this paper. Guangzhou City track GPS control network construction was taken as the breakthrough point, and our purpose was building a high precision rail transit GPS control network in exceptionally large area by combining with the existing lines, long-term planning, overall planning, and careful designing, which successfully resolved the large area of several major problems on network construction of city orbit trai c primary control. And the establishment of city rail transit GPS control network will greatly promote the application and popularization of the surveying and mapping results in the city infrastructure construction, and raise the level of social service of City Surveying and Mapping departments.
