摘要:
通过对电磁波在隧洞混凝土衬砌中的反射特征进行研究,并结合具体工程实例,阐述在隧洞衬砌质量检测中根据波形记录和雷达图像如何识别混凝土衬砌脱空、钢支撑、钢筋及保护层厚度、衬砌渗漏、衬砌厚度及衬砌混凝土内部缺陷等反射特征,从而确定隧洞的衬砌质量。

Abstract:
The reflection characteristics of the electromagnetic waves in the concrete linings of tunnels are studied. The identifying of the reflection characteristics of the lining voids, steel ribs, reinforcement bars, re-bar protection thickness, water seepage, lining thickness and lining internal defects in the quality inspection of tunnel linings by means of the waveform records and radar imags are expatiated on basis of engineering cases, so as to evaluate the quality of the tunnel linings.
Key words: ground penetrating radar, tunnel, concrete lining, quality inspection, radar image, electromagnetic wave, reflection characteristics
