摘要
IBIS-S系统是一种基于微波干涉测量技术的变形监测设备,具有高精度、高频率、整体监测的优势。为研究微波干涉测量技术在高层建筑动态特性监测中的应用,结合基于IBIS-S系统的CCTV新台址主楼的动态监测工作,介绍了试验方案和监测结果,并应用频谱分析法确定了建筑的自振特性,结果与理论计算值相吻合。试验结果证明,微波干涉测量是评估高层建筑自振特性的有效技术。
IBIS-S is a new equipment for deformation monitoring based on microwave interferometer technology,it has many advantages including high precision,high frequency and monitoring in the whole scale.The test scheme and monitoring results of the dynamic monitoring of the new CCTV headquarter based on IBIS-S were for the purposed of introduced application of microwave interferometer.The spectral analysic approach was used to obtain the vibration characteristics of the structure,the results were identical to the theoretical calculation values.The test results demonstrated that microwave interferometer is an effective technology for determining vibration characteristics of a high-rising building.
