隧道变形监测基准点的稳定性分析

对隧道进行变形监测是保证其安全的重要内容,而要保证监测结果的可靠性,就要保证监测基准点的稳定性。本文则基于国内某隧道变形监测实例,结合平均间隙法与分块间隙法,通过多期基准点观测数据,提取其中不稳定点,结果表明,该方法能准确有效分析出不稳定的基准点,提高了工作效率,为今后的隧道变形监测工程实例提供一种可靠的基准点稳定分析方法。

Stability Analysis of Tunnel Deformation Monitoring Reference Points

Deformation monitoring of tunnels is an important part of ensuring its safety.To ensure the reliability of monitoring results,it is necessary to ensure the stability of monitoring reference points.In this paper,based on the example of a tunnel deformation monitoring in China,combined with the average gap method and the block gap method,the unstable points are extracted by multi-period reference point observation data.The results show that the method can accurately and effectively analyze the unstable reference points.Improve work efficiency and provide a reliable benchmark stability analysis method for future tunnel deformation monitoring engineering examples.
