Numerical Study of Road Embankment Type Action on Shear Stress Around Skewed Bridge Abutment

This paper investigates the effect of different geometries approach embankments and guides banks on flow pattern bed shear stress values in skewed bridges compound channel using three-dimensional numerical modelling. First, model was evaluated based results existing laboratory studies. After ensuring its proper performance, elliptical guide bank three types abutments: vertical-wall, spill-through, wing-wall, at skew angles are examined. Investigation maximum velocity flow-conducting embankment flow-splitting showed that embankment, best performance is assigned to bank. In contrast, various abutments for depending angle bridge. Then, patterns streamlines geometry plan were proposed studied. The show most suitable reduces by up 15% 80% around embankments.
