摘要
基于小波分析原理,对某隧道地表监测数据进行快速去噪、提取变形特征、分离不同变形频率、估计其观测精度等处理分析,使监测结果的误差控制在±1 mm以内,并得出隧道施工对地表变形的影响规律,为隧道的安全施工和质量控制提供了依据。
Based on wavelet analysis theory,the monitoring data of a tunnel were denoised,the signals of deformation characteristics were extracted,individual frequencies of deformation were separated and observation accuracy was estimated.So the error of monitoring results was controlled at ±1mm,and the laws of the influence of tunnel construction on the surface deformation were revealed,these provided evidences for safety and quality control in tunnel construction.
