摘　　要：分析高清红外扫描技术和高频雷达技术在建筑外墙中进行渗漏水无损检测中的应用原理,并将两技术相结合应用于建筑外墙渗漏无损检测中。利用高清红外技术对建筑外墙进行整体高清扫描,利用高频雷达对渗漏部位进行切片扫描和可视化分析。研究表明,红外技术可用于确定建筑外墙发生渗水部位,高频雷达技术可检测外墙外保温系统黏结状态的同时确定系统内渗漏水的渗流路径和渗流扩散区域。This paper analyzes the principles of high-definition infrared scanning technology and high-frequency radar technology for non-destructive testing of leakage in building facades,and applying the combination of the two technologies in non-destructive testing of leakage in building facades.The high-definition infrared technology is used to scan the whole building facade in high-definition,and the high-frequency radar is used to scan and visualize the leakage parts in slices.The study shows that the infrared technology can be used to determine the parts of the building wall where water seepage occurs,and the high-frequency radar technology can detect the bonding status of the exterior insulation system while determining the seepage paths and seepage diffusion areas of the water seepage in the system.
