Prestressed Concrete Pipe Failure Jordan Aqueduct, Reach 3, United States Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

The Bureau of Reclamation conducted failure investigations to identify the cause(s) of a catastrophic rupture of prestressed concrete pipe under impressed current cathodic protection, which occurred on Reach 3 of the Jordan Aqueduct near Salt Lake City, Utah, on August 7, 1984. The multidisciplinary analyses included corrosion, design, petrographic, structural, and metallurgical investigations. From the onset of the failure, the issue was one of reconciling cathodic overprotection and defective (longitudinally cracked) prestressing wire. The report contains a summary of the findings from Reclamation investigations.
