Scour around Bridge Pier by Providing New Hybrid Collar with Opening Design for Different Pier Particulars

Abstract

Abstract: The scour around bridge piers is a very complex phenomenon. Before the designing of the bridge piers, information of the system of scour around a bridge pier is expected for any designer. For the most part disappointment of the bridge is happened because of the scouring peculiarities. In this proposal work scour around equal compound piers were experimentally studied using recirculating flume. To the satisfaction of the proposition objective, all software modelling and experimental tests run were conducted in clear water scour conditions utilization uniform non-cohesive sand with D50 (Geometric mean size of sand) equal to 1.30 mm was used with different geometry uniform piers. From openFOAM as well as experimental study analysis go for this study to reduced scouring impacts around bridge pier by providing new hybrid collar design with openings for different particulars, in the shape of a collar with openings, to be an improvement over existing FPC. New hybrid collar design with opening combination can reduced scour around 71% to 75% at upstream and 48 to 50% at downstream scour can be minimised from experimental analysis
