Title

INVESTIGATION OF FOUNDATION DEPTH AND SHAPE EFFECT ON SCOURING AMOUNT AROUND A BRIDGE PIER

Pages

  273-282

Abstract

 Scour around bridge foundations is one of the major cause of serious damage to the bridge. In this study, the effect of FOUNDATION SHAPE and level on scour process was investigated experimentally. The experiments were conducted for 4 foundations shape including; square, cylinder and aerodynamic along and across the channel and 4 FOUNDATION DEPTHs. The results showed that the scour depth depends on the FOUNDATION DEPTH and shape. The best FOUNDATION SHAPE which leads to minimum scour around it, were aerodynamic along the channel, square, aerodynamic across the channel and cylindrical shape, respectively. The results also show that by positioning the foundation below the initial channel bed, in addition to postponing in scour, leads to lower values of it. The scour depth also increases when the foundation level above the initial bed level increases. Analyses of results show that the appropriate location for positioning the foundation is 25 to 50% pier diameter.
