摘要
地质雷达是一种依靠发射超高频电磁波探测岩土体介质分布的物探仪器,在无损检测中的应用日渐广泛。阐述了地质雷达的工作原理,探讨了其应用于公路隧道工程的数据处理和图像解读方法;介绍了雷达在隧道地质超前预报和初衬质量检测中的成功应用,为公路隧道雷达监测和检测技术提供参考。
Ground penetrating radar （GPR） is a kind of geophysical instrument based on transmitting ultrahigh frequency electromagnetic wave to detect the distribution of rock and soil mass. It is widely used in nondestructive testing. This paper illuminates the principle and method of geological radar instrument, discusses its data processing anti image interpretation methods for highway tunnel engineering; introduces its successful applications in geological prediction and quality inspection of initial lining. This paper provides reference for highway tunnel monitoring and tunnel nondestructive testing.
