• Abstract:
  Each year the South Dakota Department of Transportation (SD DOT) designs and builds many cast-in-place (CIP) and precast box culvert structures that allow drainage to pass under roadways. The CIP boxes typically have 30-degree flared wing walled and the precast have straight wing walls with 4-in bevel on the inside edges of the wing walls and top slab. Previous research, SD93-12, conducted on a limited number of single barrel box culverts, indicated that further research was necessary to determine the effects of multiple barrel structures, loss coefficients of unsubmerged outlets, and to determine the effect of 12-in corner fillets versus 6-in corner fillets. In order to optimize the design of both types of box culverts, it was also necessary to determine the effects of span-to-rise ratio, skewed end condition, and optimum edge condition on typical box culvert installations"--Technical report documentation page.
