GPS测量技术在短基线控制网布设中的应用

The Application of GPS Survey Technology in the Layout of Short Baseline Control Network

针对难度系数大的桥梁隧道短基线测量,目前所采用的短基线控制网布设缺乏科学性及合理性,导致测量数据不精确、定位效果不理想。针对以上问题,本文提出了一种全新的短基线布设策略,结合GPS测量技术的应用规范设计控制网的布设网型,选择合适的控制点进行隧道测量,为实现高精度的洞内定位提供数据采集基础,并简述GPS测量技术在短基线控制网布设中的应用措施,进一步促进GPS测量技术在桥梁隧道工程测量中的应用。

Combined with the application specifications of GPS survey technology design control network layout,selecting appropriate control points for tunnel survey,this paper provides the data acquisition basis for high-precision positioning in the tunnel.And it briefly describes the application measures of GPS measurement technology in the layout of Short Baseline Control Network.This new short baseline layout strategy can further promote the application of GPS survey technology in bridge and tunnel engineering survey.
