Dynamic Simulation of High-Pile Wharf Slab under Action of Irregular Waves

The dynamic responses of single wharf slab and whole high-pile wharf structure is studied in modal analysis by 3D finite element model using software ABAQUS. According to the static force calculation module and the transient dynamics module of the ABAQUS finite element calculation, the displacement of wharf slab central point is calculated according to the effects of static force, slow variation, and the uplift pressure from both the shock and composite wave. Then the effects of wave force frequency impacting on the structure dynamic response is researched by the different high-frequency waves. These analysis results provide scientific basis and technical guidance for the high-pile wharf dynamic research in port engineering.
