摘要
为了确保上海虹梅南路越江隧道专用GPS控制网的可靠性,利用高精度全站仪测距对其进行了检测。简要介绍了各项测距改正及对应公式,描述了检测实施的过程。通过对比分析GPS测距与全站仪测距结果,判断隧道专用GPS控制网的成果符合相关规范要求,可以满足施工需求。
To ensure the reliability of exclusive GPS control network of South Hongmei Rd.Crossriver Tunnel in Shanghai,high-precision total station is used for its detection.This paper introduces different ranging correction and corresponding formulation in brief and presents the detection process in detail.By a ranging comparison and analysis of GPS and total station,the results of the exclusive GPS control network can be proved to meet the requirements of relevant standards and practical construction.
