摘要
施工期间采用地质雷达对隧道的边墙、拱腰和地表等位置进行检测,可有效保证隧道的后期运营安全。根据工程实例,利用地质雷达对尖山隧道进行了现场探测,发现隧道存在不同程度的脱空和不密实区,结果表明,地质雷达是隧道无损检测的一种可靠手段。最后综合分析了隧道存在的缺陷和原因,提出了一系列的处理措施。
To ensure the safety of tunnel operation, it is necessary to detect the side wall, arch waist and surface of the tunnel by using ground penetrating radar （GPR） during the construction. An engineering example （Jianshan Tunnel） is taken to make a detection on the spot by using GPR. It has been found that there are some different degrees of voids and non--dense areas in the tunnel, indicating that GPR is a reliable non--destructive testing method for tunnel. Finally, the reasons of the defects in tunnels are analyzed and a series of processing measurements are proposed.
