Simulation of ice accumulation around bridge piers during river breakup periods using a discrete element model
文献摘要：
During river breakup periods in winter or early spring,a large amount of ice floes of various sizes will be transported by flowing water.The presence of bridge piers in water alters velocity field.As a consequence,the transport process of ice floes around bridge piers will be influenced.It often causes the ice floe congestion around bridge piers.In the present study,the influences of the ice floe size and coverage ratio of ice floating on water surface on ice floe congestion have been examined.The influence of bridge pier layout on ice jam development has been assessed.Results showed that during river breakup period,the ice floe transport capacity around bridge pier decreased.With the presence of bridge piers,the critical coverage ratio of ice floating on water surface for the ice floe congestion depends on the ratio of the side length of ice floe to the pier spacing distance(a/Ln)and ice floe-length Froude number associated with the ice floe length(Fra).A discrete element model(DEM)has been developed to simulate the ice floe accumulating process around bridge piers.Simulation results agree well with those of experiments.
