SPH Simulation of Solitary Wave Impact on Coastal Bridge Superstructures

Sea-crossing bridges are built for connecting important coastal cities. These bridges are subjected to extreme ocean wave actions, which pose serious threats to the bridges. In this context, this study examines the solitary wave impacts on a suspended flat plate and a coastal-bridge deck numerically by using the SPH (Smoothed Particle Hydrodynamics) open-source code SPHinXsys. The physical quantities including the wave profile, the velocity distribution near superstructures and the impact load on superstructures will be investigated. The research findings will provide some guidance on how to consider the extreme wave impacts in the design and maintenance of sea-crossing bridges.
