在役桥梁快速化检测技术探讨

Discussion on Rapid Detection Technology of Existing Bridge

随着我国基础建设计划的深入,我国拥有的桥梁数目急剧增长,但是近年来由于负载问题、环境因素及结构缺陷等因素的影响,使桥梁产生性能衰退、安全性降低的问题,从而导致桥梁使用寿命大幅下降,甚至出现严重的安全问题,造成极大的社会影响。而通过先进有效的方法对桥梁结构进行合理的试验检测与诊断评估是对在役桥梁进行预防性养护管理、科学维修加固的重要手段。结合当下最常见的几种测量技术来简单探讨如何实现在役桥梁的快速化检测工作,希望能对桥梁的检测工作有所裨益。

With the deepening of China's infrastructure plan,the number of bridges in China has increased rapidly.However,due to the influence of load problems,environmental factors and structural defects in recent years,the performance and safety of bridges often decline,which leads to the decline of bridge service life,and even serious safety problems,resulting in great social impact ring.It is an important means for preventive maintenance management and scientific maintenance and reinforcement of existing bridges to carry out reasonable test detection and diagnosis evaluation of bridge structure by advanced and effective methods.Therefore,in this paper,combined with the most common measurement technology to explore how to achieve the rapid detection of the bridge in service,hoping to be helpful to the bridge detection work.
