| 摘 要： | 探地雷达作为一种高效、先进的无损检测设备,能够对隧道衬砌实施连续扫描,获得形象直观的探测图像,在公路隧道衬砌空洞检测中获得了广泛的应用.然而,由于探地雷达在我国的应用时间还非常短暂以及雷达图谱的复杂性,因此探地雷达空洞图谱的辨识还存在一定的问题.据此,通过空洞模型实验和隧道衬砌空洞现场实验,研究了模型空洞和公路隧道衬砌实测空洞的探地雷达图谱特征.在对实验数据及图像进行全面分析和对比之后,得到空洞探地雷达图谱的特征,据此提高隧道衬砌空洞探地雷达图谱的判读精度.

| Abstract: | As an efficient and advanced non-destructive detection device,ground penetrating rada(rGPR)can scan the lining of tunnels successively and obtain objective and accurate images.GPR has been widely used in highway tunnel inspection.However,GPR is not adopted for a long time in China and the radar images are very complex,and there are still some problems in the identification of radar images about cavity.Accordingly,the features of GPR images of cavity models and highway tunnel lining cavity are researched thr... |
