摘　　要：GPS技术已被引入大地测量,在公路的勘测设计中也已得到迅速推广。对于特殊工程进行控制测量时,GPS测量和常规测量在观测和数据处理中有所不同。本文通过对郑州黄河二桥特大型桥梁的实地控制测量,以说明GPS在郑州黄河二桥测量中控制网的建立原则、精度的作业方法。The technology of GPS has been introduced in ground survey, and has been rapidly developed in the area of road investigating as well. When it comes to control survey of special engineering, there is great difference in the technology of survey and data processing between GPS and normal measurement. The aim of this article is to illustrate the setting principle, precision, and the work method of the control net for GPS used in the control survey of the second bridge of Zhengzhou huanghe river.
