Seismic Stability Evaluation of Alben Barkley Lock and Dam Project. Volume 1. Summary Report
Abstract
This report summarizes the results of seismological, geological, laboratory, field, and analytical investigations conducted to evaluate the seismic stability of two earth embankment sections of the Alben Barkley Lock and Dam Project, Kentucky. These represent typical sections of the powerhouse/switch-yard area and the main embankment. Detailed documentation of each of the major topical areas of this study are contained in Volumes 2 through 5 of this series of reports. The design earthquake, from the New Madrid Seismic Zone, had a body-wave magnitude of 7.5. Of particular interest in this study, was the seismic performance of silty sands in the foundation and their overall effect on the stability of these embankment sections. The results of this study indicate that large scale deformations and/or slope failure which would result in the loss of reservoir are not deformations on the order of 2 to 3 ft are expected. These deformations are relatively small in light of the fact that 28 ft of freeboard are expected to be available during the design earthquake.
