| 摘 要： | 锦赤铁路是一条高标准的国家I级铁路,为建立一套与之相适应的精密铁路工程测量体系,应建设方要求,对位于朝阳市境内的锦赤铁路三标段(ZH-03)进行了GPS控制网复测及贯通测量。结果表明,GPS网平差后坐标和点位精度满足设计与规范要求,仅有C122～C139段与原设计提供的坐标相差5～11cm,经分析认为该段原设计为一级导线,施测方法与本次复测不同,从而导致精度的差异,但其复测成果仍然是可靠的,完全满足施工放样的需要。

| Abstract: | The Jinzhou-Chifeng railway is a high standard state Class I railway.To establish a set of rigid railway engineering survey system commensurate with it,responding to construction party requirement,carried out GPS control network repetition survey and holing-through survey in Jinzhou-Chifeng railway No.3 bid lot（ZH-03） within the boundaries of Chaoyang City.The result has demonstrated that the accuracy of coordinates and point locations after GPS network adjustment are satisfied design and related criteria requirements.Only the coordinates in C122～C139 sector differ from original design provided within 5cm～11cm.After analysis has considered that the original design of the sector is first-order traverse,thus the survey method is different from this repetition survey,consequently caused the accuracy difference.But the repetition survey results are still reliable and fully meet operation setting out needs. |
