Failure Analysis of Tainter Gate Cable-Adjusting Bolts.

Abstract

The failure of cable-adjusting bolts on the Tainter gates at the Uniontown, KY, Locks and Dam is analyzed. The bolts were found to be embrittled as a result of improper heat treatment. This condition caused a loss in corrosion resistance and toughness, allowing stress corrosion cracks to develop in the bolts. Cavitation erosion pits were found at the site of some of this cracking. Corrective measures are recommended to restore the corrosion resistance and toughness of the embrittled bolts.
