• Abstract:
  Signifi cant anomalies have been observed in many of the recently drilled shaft constructions ; throughout Louisiana. The anomalies typically occur in the form of honeycombing within the ; zones of heavy reinforcement or sometimes at the shaft bottom. Self-consolidating concrete ; (SCC) has shown great potential to overcome the diffi culties noted in some pilot studies. As ; an example, SCC was used in the drilled shafts for the Huey P. Long Bridge in New Orleans, La, ; and performed satisfactorily. However, when conventional concrete was used for the Audubon ; Bridge in Louisiana, problems were noted in the construction as well as the shaft resistance. Both ; projects consist of large size shafts constructed in the Mississippi River under similar conditions. ; One possible explanation for the diff erences in shaft performance is the concrete mixture design.
