摘要
结合横山、兴旺峁隧道群测设工作,介绍了GPS控制系统的设计思路、技术指标、平差方法以及具体施测步骤,最后为验证GPS平面控制网的可靠性,用全站仪测量部分关键三角形,并对两套数据进行精度比较。
Combining with measurement work of the Hengshan and Xingwangmao tunnel, it introduces the GPS control system's design thought, technology index, adjustment method and concrete implementation procedures, finally proves responsibility of the GPS plane control net, measures partial key triangle based on the total station, and gets precision comparison on two sets of data.
