Seismic Stability Evaluation of Alben Barkley Lock and Dam Project. Volume 4.Liquefaction Susceptibility Evaluation and Post-Earthquake Strength Determination

摘要

This report documents the results of seismological, geological, laboratory,field, and analytical investigations conducted to evaluate the liquefaction potential of two earth embankment sections of the Alben Barkley Lock and Dam Project, Kentucky. these sections are representative of those of the main embankment and powerhouse/switch-yard areas. 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 evaluation of the liquefaction potential of silty sands in the foundation.
