摘要
探地雷达用于堤防无损检测具有传统隐患排查方式无可比拟的优点。本文介绍了探地雷达检测的基本原理,通过分析其在马汊河堤防检测中所取得的成果,并与瑞利波法、瞬变电磁法互相验证,证明采用地质雷达进行堤防隐患探查可靠性较高,能满足对堤防进行定期安全检测的要求,可在我国水利工程中推广应用。
Ground-penetrating radar has many unparalleled advantages in nondestructive test of embankment, compared with the traditional troubleshooting method. In this paper, we introduced the basic principles of ground-penetrating radar, and analyzed its achievement in the nondestructive test of MaCha river embankment. In addition, ground-penetrating radar was proven to have higher reliability and meet the requirements of embankment safety test by mutually verification with the rayleigh wave method and transient electromagnetic method. Thus, it can be applied to water conservancy projects in our country.
