2、工程局管段范围为DIK28595DIK36+83543+678.46，约为13.5k m，位于河北省井陉县境内。管内共有特大桥两座、隧道四座、其余为路基及小桥涵20座。受中铁第二十工程局（甲方）的委托，石家庄铁道学院测绘工程系（乙方）对石太专用线Z7标段全线CPI CPII进行贯通复测工作。本次复测工作于2008年3月2日开始，前后分两次进行，至2008年3月20日复测外业工作全部结束。二、作业仪器及作业依据本次复测采用Leica 1230 GPS接收机4台(5mm+1ppm)，Tribmle4600 接收机6台(5mm+1ppm)，按全球定位系统(GPS)铁路测量规程 (TB10054-97
3、)及高速铁路相应测量规范，以CPI，CPII的观测要求进行施测。复测作业依据：（1） 工程测量规范（GB 0026-93）； （2） 新建铁路工程测量规范(TB10101-99)；（3） 时速200-250公里有碴轨道铁路工程测量指南（试行）（铁建设函200776号）； （4） 全球定位系统（GPS）铁路测量规程（TB 10054-97）； （5）全球定位系统（GPS）测量规范（GB/T 18314-2001）；三、复测方法3.1 GPS-C（CPI）测量：CPI控制网测量的技术要求级别项目GPS基站网的技术要求卫星截止高度角15时段中任一卫星有效观测时间（min）20有效观测卫星总数4观测时

6、，CPI1019，CPI1020，CPI1021，CPI1025，CPI1026，CPI1027，CPI1029，CPII1013，CPII1014，CPII1015，CPII1016，CPII1017 ； 其中，CPI1019，CPI1020，CPI1021，CPI1025，CPI1026，CPI1027，CPI1029，CPII1013，CPII1014，CPII1015，CPII1016，CPII1017均为设计院提供的控制点，1029-Z，1202，1206为新增控制点。4.2 GPS数据处理方法及成果说明基线解算及网平差使用Leica商用处理软件Geo Office 4.0 (LGO
7、4.0)采用广播星历进行解算，基线质量及基线网闭合差符合规程要求。网平差先在WGS84坐标系中进行三维无约束平差，然后进行二维无约束平差，然后将平差结果转换至本标段现行采用的坐标别采用Geo Office 4.0中的二维二步转换法、和武汉大学科傻软件控制测量通用软件包COSAWIN98中的二维坐标转换法进行，其结果差异甚小，基本一致。此外还将观测的外业原始观测数据转换成Rinex 格式的数据文件，利用Trimble公司的GPS数据处理软件TGO1.62进行基线解算和网平差处理，其结果均符合规程要求，其最终坐标转换结果与前述两种方法基本一致，从而验证了数据处理结果的正确性。以下只给出Leica处
8、理软件LGO 4.0处理的结果。从复测结果看，除CPI1020外，复测成果与原成果之间相差较小，可以采用CPI，CPII控制点原成果。最后在将原成果固定约束下，求得新增各点坐标。4.2 GPS复测结果GPS复测网WGS84平差结果点标识XYZ平面和高程质量1029-Z-2049583.70604585636.05293918050.65790.00861202-2057487.00844586372.17983913126.64490.00301206-2056139.41544586266.65923913919.73130.0041CPI1019-2061598.08134586067.1
