摘　　要：地基雷达是近年来建筑物微变形监测领域的一项新型监测设备,基于地面干涉雷达系统的IBIS-S微变形监测系统可对桥梁和高塔等易发生微小形变的建筑物进行精确监测。本研究利用IBIS-S系统对南京江心洲长江大桥挠度变形进行静载和动载试验测量,对该系统在桥梁监测领域的应用进行分析,可为同类项目提供参考。Ground-based radar is a new type of monitoring equipment in the field of building micro-de-formation monitoring in recent years.The IBIS-S micro-deformation monitoring system based on the ground InSAR system can accurately monitor buildings that are prone to small deformations,such as bridges and towers.This study uses the IBIS-S system to carry out deflection deformation moritoring of Jiangxinzhou Yangtze River Bridge in Nanjing with static and dynamic load.Based on this case,the ap-plication of IBIS-S system in the field of bridge detection is analyzed,which can provide reference for similar projects.
