Abstract

In this study, flow field around piers with different configurations are simulated using three-dimensional computational fluid dynamics (CFD) model. The effects induced by different cross-sectional shapes (circular, square, diamond, and lenticular), different aspect ratios, and different attack angles are studied. An expression based on the concept of effective width is proposed to evaluate the combination effect of the aspect ratio and the attack angle on the maximum shear stress. The flow patterns are analyzed and compared with the corresponding scour patterns observed from experiments to investigate the influence of pier configurations on bridge scour; these findings also shed light on the scour mechanism and help guide practice applications of countermeasures.
