Reach scale morphological process in bridge
WebMar 1, 2024 · Fluvial morphology in compound river channels usually undergoes drastic variation during extreme floods due to scour and erosion processes. Those processes … WebMar 1, 2024 · The dynamic deformation process is represented to reveal the bridge’s damage mechanism and damage modes under different floods. Analysis results indicate that the proposed model can accurately predict the performances of real bridge. The main beam is easily washed away when more than 1/2 of the volume of the beam is submerged.
