路基挖方1100万m3路基填方920万m3主线设置大桥20座，中桥1座，隧道2685m/4座，沿线设互通5处，全线（包括互通）涵洞、通道共193道。

天桥13座。

我标段设计院共交控制点107个，其中有8个控制点已经被破坏，还有7个控制点偏离主线太远，经过我方筛选，选取了92个点在我标段范围内且布设在主线附近的平面和高程控制点作为本次复测的控制点，其他的15个控制点不再本次复测范围内；

为了保证与相邻标段的顺利衔接，本次复测还加入相邻标段的3个控制点，以保证线路的顺利衔接。

控制点精度为《公路勘测规范》JTGC10—2007中一级GPS控制点，高程控制点等级为四等。

3.复测工作内容

本次复测工作内容为：

蒙文砚高速K80+073.789～K128+311.735内92个平面和高程控制点，包括与相邻标段平面和高程控制网点的联测。

4.复测工作的开展

接到本标段控制网复测的任务后，有关工作人员于2014年11月01日开始，11月30日完成全部外业测量工作，12月8日前完成全部的数据整理与平差工作，12月25日前提交所有测量报告。

参加本标段控制网复测的工作人员共15名，其中测量工程师1名，测量技师1名，外业观测的测量工13名。

复测使用的仪器设备均经测绘仪器计量检定单位检定合格，并在检定有效期内，可用于相应等级精度要求的测量工作。

5.坐标系统

采用与设计院建网时相同的坐标系统，即平面坐标系统采用高斯投影平面直角坐标系，即参考坐标系统为WGS84下面独立坐标系统。

高程系统为1985国家高程，中央子午线为104度05分，抵偿投影面1300m。

6.平面控制网复测

平面控制网复测前首先进行现场检查标石的完好性，经现场勘查本标段范围内有设计提供的点有107个，有部分控制点已经被破坏或者远离主线被弃用，最后剩余92个控制点均保护完好且均匀分布在线路附近作为本次复测点。

平面控制网复测的作业方法、精度指标、使用仪器均按公路一级GPS网精度标准进行。

6.1平面控制往复测组网实施

遵循与设计单位建网时相同的构网原则，本次控制网复测组网以大地四边形或三角形为基本构网图形组成带状网，采用网联式构网。

平面网复测组网观测的基本要求：

作业前按要求进行仪器检校。

对中设备采用精密对点器，对中精度小于1mm，在作业前及作业过程中对基座水准器、光学对点器进行检校，确保其状态正常。

观测严格执行调度计划，按规定时间进行同步观测作业。

使用7台GPS接收机进行作业。

采用同步静态观测模式。

平面控制网点与四等GPS点的联测按四等测量精度进行。

平均重复测站次数≥1.6次/每点，每时段观测不少于40分钟。

为了保证足够精度,本次复测观测时间均超过45分钟控制。

作业过程中，天线安置严格整平、对中。

卫星高度角设定为15°

，数据采样间隔设定为15秒，确保同步观测有效卫星数不少于4颗。

每时段观测前后分别量取天线高，误差小于2mm时取两次丈量的平均值作为最终结果。

作业中使用对讲机需离GPS接收机10m以外。

一个时段观测结束后，重新对中整平仪器，再进行第二时段的观测。

观测人员严格按手簿内容进行详细记载，不得错记、漏记，严禁事后补记或伪造。

6.2平面控制网基线解算分析

复测基线解算采用广播星历，用LGO7.0/TBC2.5商用软件按静态相对定位模式进行，采用双差固定解求解基线向量。

外业观测结束后，以大地四边形作为基本构网图形对观测基线进行处理和质量分析，检查基线质量是否符合相关规范的要求。

a）基线向量异步环闭合差

基线向量异步环闭合差是检验基线向量网质量的一项重要技术指标。

在解算出每一时段的基线向量后，以三角形作为构环图形，在不同时段间组成异步基线环，并计算该异步环坐标分量闭合差。

基线向量异步环闭合差应符合下式规定：

Wx≤

*σ

Wy≤

Wz≤

W≤2

上式中，n为闭合环边数（n=3），σ为GPS基线向量弦长中误差（

mm，d为实际环的平均边长，单位km）。
