地质雷达在铁路隧道检测中的应用及典型图像分析

The Application and Typical Image Analysis of Ground Penetrating Radar in the Detection of Railway Tunnel

采用地质雷达进行铁路隧道衬砌质量检测,不仅具有快捷、准确的特点,而且还能进行实时处理与显示。总结了温福铁路(福建段),福厦铁路及赣龙铁路扩能改造工程(福建段)隧道衬砌检测的情况,以隧道常见的典型雷达数据为工程实例,浅谈地质雷达在铁路隧道工程中的应用,说明地质雷达可以及时、准确、客观地反映隧道衬砌病害情况,从而为施工单位早期制定方案、整治处理,消除工程隐患提供科学依据。

The quality inspection of railway tunnel lining by ground penetrating radar has the characteristics of quick, accurate,but also can be real- time processing and display. In Summing up the tunnel lining quality inspection situation of Wenfu Railway（Fujian section）, Fu Xia railway and Ganlong railway expansion renovation project（Fujian section）, taking the common typical tunnel radar data as a project case, the paper discusses the application of ground penetrating radar in railway tunnel engineering, and illustrates that the ground penetrating radar can timely, accurately and objectively response to tunnel lining disease situation, so then provide scientific basis for construction unit to make early plans, to repair and to eliminate hidden dangers.
