摘要
桥梁结构在长期使用过程中容易出现损伤,影响其结构安全性,传统检测方法依赖于人工检查和局部检测存在一定局限。振动测试的损伤识别技术凭借其高效、无损的特点,逐渐成为桥梁健康监测的主流方法。文中分析了振动测试技术基本原理,研究了损伤模态参数分析、损伤定位定量分析等关键技术,提出了基于振动测试的桥梁结构损伤识别新方法,旨在实现桥梁损伤的精准识别与定位。
Bridge structures are prone to damage during long-term use,which affects their structural safety.Traditional detection methods,which rely on manual inspections and localized assessments,have certain limitations.Damage identification technology based on vibration testing has gradually become a mainstream method for bridge health monitoring due to its efficiency and non-destructive characteristics.This paper analyzes the basic principles of vibrtion testing technology,studies key techniques such as damage modal parameter analysis and damage localization quantitative analysis,and proposes a new method for bridge structure damage identification based on vibration testing,aiming to achieve accurate identification and localization of bridge damage.
