Characteristics of Developing Scour Holes around Two Piers Placed in Transverse Arrangement
Local scour at single pier has been extensively studied by several investigators, but scanty work is available on scour around bridge piers founded in close proximity. The work reported herein is concerned with a carefully controlled extensive experimental study of local scour around a group of two bridge piers placed in transverse direction to the flow at varied pier spacing under steady uniform flow clear water scour conditions at flow intensity equal to 0.95. The objective of present study is to investigate the effect of mutual interference of bridge piers on local scour. The data on temporal scour depth, areal extent of scour and sediment deposition around the piers and scour hole characteristics are collected which may provide very useful information to the bridge engineers. Present study reveals that the piers founded in transverse direction to the flow at close proximity may lead to bridge failure, if pier group effect is ignored and bridge piers are designed merely as an isolated pier.
