Abstract

Abstract: Wavelet filtering and EMD filter were applied to the GPS dynamic observation data filtering, and an EMD combined wavelet filtering method was put forward for the applilation of wavelet filtering and spectrum analysis to the EMD decomposition. These three filtering methods were applied to the bridge dynamic monitoring data processing in combination with evaluation index analysis, and calculation results show that the EMD combined wavelet filtering method performs better than the other two.

Key words: bridge engineering, wavelet analysis, GPS, EMD, spectrum analysis, filtering

摘要： 将小波分析滤波、EMD滤波应用于GPS动态观测数据滤波，并提出一种EMD小波组合滤波方法，该方法将小波滤波和频谱分析应用于EMD分解。将3种滤波方法应用于桥梁动态监测数据处理，结合评价指标分析，计算结果表明:EMD小波组合滤波方法滤波效果优于小波滤波、EMD滤波。
