摘要
文中利用BDS/GPS组合技术对国内某复杂环境超高层进行变形监测,并基于希尔伯特-黄变换提取该超高层的模态参数。经研究发现,BDS/GPS组合下,增加了卫星可见数,改善了卫星空间几何结构,提高了变形监测精度,希尔伯特-黄变换能根据BDS/GPS实测数据准确提取超高层模态参数,为今后超高层的修缮与维护提供可靠的数据支撑。
In this paper,BDS/GPS combined technology was used to monitor the deformation of super high-rise building in a complex environment in China,and the modal parameters of the super high-rise building were extracted based on Hilbert-Huang transform.Research founded that under the BDS/GPS combination,the number of visible satellites was increased,the spatial geometric structure of the satellite was improved,and the deformation monitoring accuracy was improved.Super high-rise modal parameters could be accurately extracted based on the measured data of BDS/GPS by Hilbert-Huang transform,providing the reliable data support for the repair and maintenance of the super high-rise buildings in the future.
