非接触式自由设站隧道监控量测方法

A Non-Contact Measurement Method of Free Station for Tunnel Monitoring and Measurement

传统的观测方法在现场实施过程中存在许多问题,为此提出了全站仪非接触式自由设站隧道监控量测方法,并详细介绍了此方法的原理和数据的采集及处理分析方法。通过合福铁路安徽段隧道监控量测的实例分析,证明此方法不仅消除了仪器高和觇标高误差,而且在隧道监测方面具有明显的优势。

With the development of modern tunnel,the traditional measurement methods have been already unsuitable. This paper proposes a non-contact measurement method of free station for tunnel monitoring and measurement and introduces the principle and the process of data collection and analysis. Through the case study of tunnel monitoring and measurement in Anhui section of Hefu railway,the proposed method not only eliminates the height error of meter and prism,but also has significant advantages in tunnel monitoring. The advantages and application prospects in other aspects are also presented in this paper.
