Abstract
The present invention discloses a bridge inspection and evaluation method based on impact vibration. The method includes backward analysis of the bridge based on impact on blocks without reference points and forward analysis of the bridge based on progressive impact loading, where the backward analysis of the bridge based on impact on blocks without reference points is used to rapidly inspect the medium and small bridges from the road network to find the ones with serious shortage of bearing capacity, and the forward analysis of the bridge based on progressive impact loading is used to evaluate the actual bearing capacity of the bridges, which may have good safety condition in the backward analysis. The present invention realizes low-cost and highly efficient inspection and evaluation of the medium and small bridges in the road network.
