桥梁损伤安全评定方法研究

摘要

介绍了桥梁结构的损伤机理，探讨了桥梁损伤诊断的几种方法，并从外观检测、设计规范、荷载试验、层次分析等方面，阐述了桥梁损伤安全评定的常用方法，比较了各种方法的优缺点，有利于桥梁工程选择适宜的评定方法。%The PaPer introduces the bridge structure damage mechanism,exPlores several bridge damage diagnosis methods,describes common bridge damage safety evaluation methods from asPects of aPPearance detection,design norms,loading test and hierarchical analysis,and finally comPares their merits and defects,which will be good for selecting suitable bridge engineering evaluation methods.
