雪峰山特长隧道平面控制测量基准的建立

ESTABLISHMENT OF PLANE CONTROL SURVEYING DATUM FOR THE EXTRA-LONG TUNNELIN XUEFENG MOUNTAIN

介绍了GPS技术应用于雪峰山特长隧道工程平面测量基准建立的方法,分析了GPS控制网的观测质量,并就GPS控制测量误差对隧道横向贯通误差的影响值进行了估算。

This paper introduces to use GPS techniques to establish the coordinate basis for the king|size Xuefengshan Tunnel . The observed qualities of GPS network are analyzed,and the errors of piercing are predicted.
