NettetWingwalls in abutment and semi-integral abutment bridges are designed as retaining walls to avoid the sliding of the backfill soil behind the bridge abutments and roadways. Using turn-back wingwalls that are parallel to the bridge diaphragm can provide support for the parapets and minimize the total longitudinal pressure on the abutments. NettetIntegral wingwalls begin either at the edge of superstructure, face of backwall or the edge of abutment prominence, if present. For the example shown, the abutment is a sill abutment with an integral concrete wing attached with no joint between the two.\r\ Published by Articulate® Storyline www.articulate.com 1.15 Untitled Slide
