光纤光栅传感技术在高速公路隧道围岩变形实时监测中的应用

APPLICATION OF FIBER BRAGG GRATING SENSOR TECHNOLOGY IN HIGHWAY TUNNEL SURROUNDING ROCK DEFORMATION AND REAL-TIME MONITORING

  • 摘要: 公路隧道工程的监测环境复杂,监测对象受到时空限制和施工环境制约,基于传统的机电测试技术的监测方法,很难实现远程实时动态监测。结合张涿高速东马各庄隧道工程实时监测数据库,采用光纤传感技术对张涿高速东马各庄隧道实现了远程实时监测。通过对监测成果进行整理,得到不同级别围岩的变形量、变形稳定时间、变形速率,提高了围岩稳定性时间,对类似工程具有很大的指导意义。

     

    Abstract: The monitoring environment is complex for highway tunnel engineering, and monitoring objects are constrained by time and space limits as well as construction environment. It is difficult to realize the remote and real-time dynamic monitoring by using the monitoring method based on traditional mechanical and electrical testing technology. Combining the real-time monitoring database of Zhang Zhuo high-speed east Magezhuang tunnel engineering, and using optical fiber sensing technology, remote and real-time monitoring is realized. By sorting the monitoring data, the surrounding rock deformation, stability time, and deformation rate in different levels are obtained. The surrounding rock stability are improved, and it has a great guiding significance for similar projects.
