由于隧道混凝土检测的性质影响,其检测质量受到很大限制,采用传统方法效率低,且破坏原始结构的整体性。地质雷达能够连续的并且全面精确的对衬砌结构无损伤进行检测。本文介绍了地质雷达检测隧道衬砌质量的基本原理、方法,并以工程实例对一些典型的隧道衬砌地质雷达图像作出解释说明。
Due to the nature of tunnel concrete testing, the quality of testing is greatly limited. The traditional method is inefficient and destroys the integrity of the original structure. Geological radars are capable of detecting continuously and completely without damage to the lining structure. This paper introduces the basic principle and method of detecting the quality of tunnel lining with GPR, and explains some typical tunnel lining GPR with engineering examples.
