公路桥梁无损检测技术及应用

On nondestructive testing of road bridges and its application

阐述了对桥梁结构进行病害和损伤检测的必要性,重点介绍了回声波检测法、探地雷达检测法、射线探伤法等几种无损检测技术,以及无损检测技术在桥梁工程中的应用,以期促进我国桥梁检测技术的发展,为公路桥梁的检测和维护提供了一些指导。

The paper indicates the necessity of the diseases and destructive testing of the bridge structures,introduces some nondestructive detection techniques,including the echo sound wave test method,the Ground Penetrating Radar detection,and the ray flaw detection method,and the application of the nondestructive detection technique in bridge projects,so as to enhance the development of the bridge detection technique in China and provide certain direction for the test and the direction for the road bridges.
