| Abstract: | 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. |
