Abstract:: Aimed at the representative project in the piers,which is protected by the downstream sediment storage dam,this paper has studied three dimensional velocity field in local scour areas around piers via mathematical simulation.The validated results are better contrasting that of the model test surveyed by ADV (Acoustic Doppler Velocimeter) while the influences of shaping eroded pits caused by the velocities in different directions are analyzed.The mathematical simulation method of velocity field in local scour pit around bridge pies can be referenced to study local scour around bridge pies and complicated boundary flowfield theory in depth.The distribution of velocity field in local scour pit near piers protected by the sediment storage dam,deduced from the paper,will provide references for defensive design of bridge projects with pies in low burial.
