摘 要：The process of tidal bore passing through bridge piers is numerically simulated in an open channel using a pure Lagrangian method,*** Particle Hydrodynamics（SPH）.Due to its gridless feature,SPH is intrinsically wellsuited for the complex hydrodynamic simulation when the fluid encounters a *** behavior of bores propagation along the channel is illustrated herein and includes the bore’s free surface properties and flow field,and in particular,the intricate behavior of unsteady flow during the passage of tidal *** generation of shock waves between the structures can be clearly observed in the numerical *** vortical structures behind the bore front are generated as the bore propagate through the constriction.
