GPS控制测量技术总结1.doc

通渭县马营至陇西县云田公路工程MY4合同段GPS控制测量技术总结一、测区概况 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
