地质雷达法与冲击回波法在铁路隧道衬砌质量检测中的综合运用

Comprehensive Application of Ground Penetrating Radar Method and Impact Echo Method in Quality Inspection of Railway Tunnel Lining

铁路隧道衬砌质量检测要求较高,地质雷达法作为一种成熟的物探技术,在铁路建设领域一直发挥着不可替代的作用,同时一些无损检测的新方法如冲击回波法等也开始运用在隧道衬砌质量检测中。对地质雷达法与冲击回波法的基本原理进行简要介绍,分析这两种方法在检测过程中存在的一些问题,并对这两种方法进行对比及验证。研究表明,综合运用地质雷达法与冲击回波法对隧道衬砌质量进行检测,可以取得较好的效果。

There are high quality inspection requirements for railway tunnel lining.As a proven geophysical exploration technology,the geological radar method has always played an irreplaceable role in the field of railway construction.At the same time,some new non-destructive testing methods such as the impact echo method,have also begun to be applied in the quality inspection of the tunnel lining.In this study,the basic principles of the geological radar method and the impact echo method are briefly introduced,some problems that exist in the testing process of these two methods are analyzed,and these two methods are also compared and verified.Research has shown that the comprehensive application of the geological radar method and the impact echo method to inspect the quality of the tunnel lining can achieve good results.
