摘要
以张承高速公路东山隧道二衬检测为例,阐述了采用地质雷达对隧道进行检测的原理及方法,对实例检测得到的波形图进行解释并得出结论,以此作为二衬质量评价的依据;再对隧道同一部位采用钻探取芯法进行复测,结果两种方法吻合较好。说明地质雷达检测结果具有较高的可信度。
Taking Dongshan Tunnel secondary lining detection of Zhangjiakou-Chengde Expressway,this paper describes the principle and method of tunnel detection using geological radar.It explains waveform graph obtained from the example and gets conclusion.Based on this conclusion as the secondary lining quality evaluation,the same section of the tunnel is retested using core drilling method.It is proven that the results from the two methods are in good conformity.Therefore it is indicated that geological radar detection result has higher reliability.
