Application of GPR Technology to Nondestructive Test of Bridge Structure

探地雷达在公路桥梁无损检测中得到广泛的应用,在阐述探地雷达无损检测技术的原理和方法的基础上,结合工程实例说明了高精度探地雷达在公路桥梁无损检测中的应用,及其无损、简易、效率高、精度高、抗干扰能力强的优点,为准确评价桥梁结构质量提供了科学依据。

Ground penetrating radar on highway bridge nondestructive test has been widely applied. In this paper,on the basis of elaborating the principles and methods of GPR nondestructive test, by combining with an example to show the application of high precise GPR to highway bridge nondestructive testing, and the advantage of non-destructive, simple, high efficiency, high precision, strong anti-interference capability of GPR is explained. An scientific basis is provided for accurate evaluation on the bridge structure quality.
