摘要
白浩铁路一期工程线路自桑锡线的白音库伦车站引出,直至门迪诺尔,全线长约52.253km。根据野外施工条件采用GPS定位技术进行E级网平面控制测量,高程控制采用几何水准方法,在施测时加测一个临时点以增加图形强度。测量施工采用4台S82-2008双频GPS接收机按静态观测方法进行同步观测,观测时间控制在45min^60min。根据GPS网平差后坐标和点位精度分析,该项勘测工程控制网设计与施工措施合理,测量结果满足规范所规定的各项限差要求。白浩铁路一期工程GPS施测控制网的布设方法为GPS在沙漠地区特殊条件下的应用提供了一成功例证。
The first-stage construction of the Bayin Hure-Holai Hure railway is led off from the Bayin Hure station on the Sanggin Dalai-Xilinhot railway straight to the Mendi Nut with full length about 52.253km. Based on field constructional conditions, the GPS positioning technology is used in the E grade network horizontal control survey, geometrical leveling in vertical control, one provisional point is added in surveying to enhance the strength of figure. 4 S82-2008 dual-frequency GPS receivers are used in static simultaneous observations, 45min-60min observation times are controlled. Based on GPS network error compensated coordinate and point position accuracy analyses, the control network design and operational measures of the surveying engineering are deemed to be reasonable, and the results can meet code specified each tolerance requirement. The GPS survey control network layout method in Bayin Hure-Holai Hure railway first-stage construction has provided a successful example for the application of GPS under the particular conditions in desert areas.
