摘要
通过对桥梁结构拓宽加固后自振频率检测技术的应用进行具体分析,并利用有限元分析法结果进行比较,结果表明两者较为吻合,可为旧桥改善后的效果评估、检测、拓宽后新旧桥是否协同工作的评估以及对新桥的设计提供必要的依据,具有重要的指导作用。
This paper analyzes mainly the application of natural vibration frequency inspection （NVFI） in old bridge widening engineering. Compared analysis of NVFI with FEM （finite element method）, the result of inspection is reasonable. It offers essential and important proofs to examine and evaluate the effect of the reconstructed old bridge and the design of new bridge, and also has important guidance value.
