特大桥施工控制网测量技术

摘要

Taking Beige Tai-Chang highway bridge as an example,the paper illustrates the extra-large bridge construction control network meas-urement technology points and working procedures,and introduces detection methods of different GPS network. Through examination analysis ,it points out that:applying GPS technology into extra-large bridge construction control will improve the bridge control accuracy.%以北格太长高速公路特大桥为例，阐述了特大桥的施工控制网测量技术要点及作业流程，并介绍了不同的GPS网观测作业方式，通过检核分析，指出GPS技术应用于特大桥施工控制网测量，可提高桥梁平面控制网的精度。
