The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...
Testing and Evaluation of High Capacity, Multi-Strand Rock Anchors for Lake Lynn Dam
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...
Remedial Works at Troneras and Miraflores Dams in Colombia
The 38 m high Troneras and the 55 m high Miraflores earth dams were built in the period 1959-1965. The dams are composed of residual soils and founded on a deep residual overburden. Significant...
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Conversion of a Concrete Slab and Buttress Dam to a Gravity Dam
The 58-foot high, 425-foot long, Ambursen-type, concrete slab and buttress, Gorge Plant Dam, which has a 120-foot long overflow spillway near the center, was converted to a concrete gravity...
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
Liquefaction Potential Leads to Dam Reconstruction
Results of a visual inspection of the Dundee Dam conducted in 1982 revealed the presence of seepage on the downstream toe of the left embankment. Subsequent subsurface explorations and...
Stability of Embankments, Fills and Structures at the Bad Creek Project Under Static and Dynamic Loading
Duke Power was faced with the problem of using explosives to assist in removing a sensitive, saturated embankment cofferdam supported on a large rock plug. The first phase of the work...
