地质雷达作为一种高分辨率和高准确率、并且快速高效的探测技术而得到迅速推广和应用。本文结合近几年在铁路隧道质量检测中的工程实例,阐述了地质雷达技术在铁路隧道衬砌质量检测中的应用特征及效果。并对一隧道实体检测的隧道衬砌典型雷达图像的识别进行了概述,为类似检测提供参考。 Geological radar as a high-resolution and high accuracy, and fast and efficient detection technology has been rapidly promoted and applied. Based on the engineering examples of railway tunnel quality inspection in recent years, this paper expounds the application characteristics and effects of GPR technology in railway tunnel lining quality inspection. This paper also gives an overview of the typical radar image of tunnel linings detected by a tunnel entity, and provides reference for similar detection.
