Bluff Erosion Stabilization for the Shelby Dell Transmission Tower
Structure 67 at Tennessee Valley Authority’s Shelby Dell transmission line sits 175 ft (53 m) above the Mississippi River, adjacent to a bluff that has experienced about 300 ft (91 m) of erosion since the late 1980s. The soil conditions at the bluff include collapsible loess near the top of the profile, and stiff clay that is susceptible to river scour below. The rate of erosion was estimated at 8–20 ft (2.5–6 m) per year. The project team designed a steel sheet pile wall with tiebacks to protect the tower. The sheet pile wall was designed to resist up to 20 ft (6 m) of erosion down its face, adding an estimated year or more of protection from bluff erosion for the tower. This paper provides an overview of the erosion evaluation, alternative repairs considered, sheet pile wall design and construction, and monitoring of the bluff during construction.
