摘　　要：传统大型桥梁工程测量控制网的建立多采用经纬仪、测距仪、水准仪、全站仪等测量设备来建立测角网、测边网或边角网。这些手段采集数据多、工作量大,作业时间长,受气候、通视等环境条件影响误差积累多。随着科技的不断进步以及测绘技术的不断发展,GPS测量技术被广泛应用在高速公路、铁路等大型桥梁工程平面控制测量施工中,它具有效率高、精度高及成本低的特点。The traditional engineering surveying of large-scale bridge set up the control network always uses the theodolite, diastimeter,level instrument, total station and so on, all these equipments are used to set up the angle measurement network, trilateration network and triangulateration network. These methods has the characters such as large data amount, heavy workload, long work time, affected by climate, intervisibility and other environment,which has accumulation error. With development of science and technology, the GPS surveying technology has been wildly applied in large scale bridge plane control survey construction in highway, railway and other project, it has the characteristics of high efficiency, high precision and low cost.
