摘　　要：为了验证奇异谱分析提取高层建筑物振动特性的有效性,采用了奇异谱分析方法处理高层建筑物GPS振动观测数据。实验发现:通过合理选择奇异值的有效成分,能够提取观测序列的主要趋势、周期、噪声,在提取信号周期、振幅和频率方面要优于小波分析。In order to verify the effectiveness of extracting the vibration character of tall building by singular spectral analysis, the singular spectrum analysis method is applied to process the tall building GPS vibration observation data. The test shows that：Through choicing the effective components of singular value reasonably, the main trends, cycles, and noises of the observation sequence can be extracted. In the aspect of extracting the signal cycle, amplitude and frequency, it is better than wavelet analysis.
