Effect of Stream-wise Spacing of Bridge Pier on Local Scour Depth of Circular Piers A Project

Abstract

One of the main causes of the bridge failures scour around its piers and abutment. Requirement of new bridge in the close vicinity of existing one is increased day by day due to rapid urbanization and increased traffic volume the structures of the flow significantly altered due to the presences of an obstruction for example a pier n the flow. The situation even more complex when a bridge is constructed in the close vicinity of existing one. The proposed new bridge interfaces the flow geometry. This interference also depend upon the stream wise spacing between the bridge .The main objective of the present work is to find the optimum distance between the two bridge so that new bridge constructed in the vicinity of old bridge or vice versa by studying the mechanism of scour ad scour depth at bridge pier.Keeping the objective in mind, Present work is carried out through the set of laboratory experiment conducted in the hydraulic laboratory of civil engineering department JUIT waknaghat. The present investigation will be an add to design the new bridge in proximity of old one.
