GNSS高层建筑位移监测数据分析

GNSS High-rise Building Displacement Monitoring Data Analysis

如今GNSS技术快速发展,在实际工程中常利用该技术对高层建筑进行变形监测,确定高层建筑的安全性以及稳定性。本文基于某一高层建筑实测的GNSS动态监测数据:验证数据质量的完整性;对数据进行数据插值,弥补缺失数据;利用小波分解以及快速傅立叶变换对数据进行处理和分析,得到频谱图,发现建筑存在固定的周期性的振动。

Currently,GNSS technology is developing rapidly,and it is often used to monitor the deformation of high-rise buildings to determine their safety and stability.Based on the measured data of GNSS dynamic monitoring for a high-rise building,this paper verifies the integrity of the data quality;Interpolate data to compensate for missing data;Using wavelet decomposition and fast Fourier transform to process and analyze the data,a spectrum diagram is obtained,and it is found that there are fixed periodic vibrations in the building.
