Wingwall layout and orientation
Wingwall layout and orientation
(OP)
Is there a quick method for setting the orientation and length for splayed wingwalls on cantilever or stub abutments?
I've always been taught to draw the proposed grading contours and to lay the wingwalls out using that method. However, this is time consuming for preliminary design. Are there any shortcuts or rules-of-thumb out there?
Thanks!
Tom

On non-skewed bridges with equal rates of embankment slope in front of the abutment and along the roadway 45 degrees yields a pretty efficient wingwall layout. However, what about cases where the bridge is on a large skew, is located along a horizontal curve, or the rates of embankment sideslope are not equal? Is it that the old standby of developing contours is really the only reliable method of developing the wingwall orientation and layout.
