本项目路线起点自主线K16+500，终点榜罗镇街末端K29+485处。沿线经通渭县什川镇高庙山村，双峰村，全线均在通渭县境内。大多沿原有公路取直加宽进行改造。全长25.888km。 本项目所经地段处陇西黄土原岭、梁地貌，地形北高南低，海拔高度在21301930米之间，相对高差200米。项目途径区域河流为渭河支流魏家长河、干沟河，地表均被黄土覆盖，黄土层深厚，厚达1030m。地下水质多为矿化度很小的重碳酸钙型塬区黄土层空隙潜水。本项目工程施工及稳定性均不受地表径流、潜水及地下水的影响。沿线地质总体情况良好，但均属湿陷性黄土，不良地基有黄土陷穴、垮塌、翻浆等。二、规范标准全球定位系统实时动态测量（RTK）技术规范（CH/T2009-2010）三、坐标系的选择 GPS网的平面坐标系统采用2000国家大地坐标系（CGCS2000），高程系统采用正常系统，基准为1985国家高程基准。 四、仪器设备和软件 GPS控制测量采用广州三鼎光电仪器有限公司三鼎T20(RTK)型GPS测量系统，带有SBAS星站差分功能2854通道的接收机，预留72通道升级包括：14通道GPS L1+2通道SBAS14通道GPS L2通道12通道GLONASS L1通道（支持）12通道GLONASS L2通道（支持） 静态平面精度： 3mm+1ppm,静态高程精度： 5mm+1ppm，静态作用距离：优于100公里静态内存：内置64MRTK平面精度：1cm+1ppmRTK高程精度：2cm+1ppmRTK作用距离：优于8公里RTK初始化时间：典型15秒数据通讯：标准USB协议，USB2.O,串口（RS-232）,蓝牙数据链：GPRS/CDMA（内置）/25M(内置)内置GPRS/CDMA网络通信部分支持GPRS/CDMA通信服务，国际通用，自动网络登录，兼容各种CORS系统的接入物理指标：尺寸：高96mm,直径184mm,密封橡胶圈到底面高60mm重量：1.2kg（带电池）单块电池容量：2400mAH电压：7.4V，单块电池连续工作时间可达6到8小时可外接直流电，宽输入范围12到15V,内外电源自动切换等级：IP67高 程 （10mm+2ppmD） 三鼎T20(RTK)型GPS测量系统配备有Planning星历预报软件（可预报30天内测区各测点一天24小时的卫星分布状况及健康状况）三鼎T20(RTK)型GPS测量系统后处理解算软件（包含数据传输、基线向量处理、GPS网平差软件、多种GPS数据格式转换等功能），完全能满足GPS控制测量数据处理的要求。 GPS实测和数据处理时采用的其它设备移动电话、计算机和必要的交通工具等。 五、四等GPS网的设计和观测
