摘要
为研究地基雷达在高层建筑物动态监测中的应用,介绍了基于IBIS-S的南京紫峰大厦动态监测实验方案和监测数据。通过数据分析可知,所选监测点位移变化量的相关性均超过了0.95;所选监测点的变化趋势保持一致,且利用所选监测点频谱图分析了紫峰大厦主楼的振动特性,得到了四阶频率。实验结果表明,地基雷达IBIS-S是进行高层建筑物动态监测的一种有效手段。
In order to study the application of ground-based radar in the dynamic monitoring of high rise building,we introduced the test scheme and monitoring data of Nanjing Zifeng Tower dynamic monitoring and testing system based on IBIS-S.The data analysis results showed that the correlation between the changes of displacement monitoring points selected were more than 0.95,the change trend of the selected monitoring points remained the same.And then,we used the spectrum analysis of selected monitoring points to analyze the vibration characteristics of Zifeng Tower,and got four-order frequency.The test result shows that the ground-based radar system IBIS-S is an effective method for the dynamic monitoring of high rise building.
