摘要
公路桥梁常见裂纹、鼓包、孔洞、脱空等隐性病害不仅对桥梁的耐久性造成影响,而且成为人们安全出行的隐患。传统检测技术无法直接观察到公路桥梁的隐性病害及其扩展情况,新型无损检测技术的发展则对桥梁隐性病害的检测提供了较为简便可行的方法。本文主要介绍了桥梁隐性病害检测中应用较为广泛的几种无损检测技术,红外热像检测技术、超声波检测技术、脉冲回波法、探地雷达检测技术,并结合最新的研究进展对桥梁无损检测技术的发展进行了展望。
Common cracks in highway bridges,hidden diseases such as bulges,holes,and voids not only affect the durability of bridges,but also become a hidden danger for people’s safe travel.The traditional detection technology can not directly observe the hidden diseases and extension of highway bridges.The development of new non-destructive testing technology provides a simple and feasible method for the detection of hidden diseases of bridges.This paper mainly introduces several non-destructive testing techniques widely used in the detection of bridge hidden diseases.Including infrared thermal image detection technology,ultrasonic detection technology,pulse echo method,ground penetrating radar detection technology,combined with the latest research progress,the development of bridge nondestructive testing technology is also prospected.
