Site-Specific Earthquake Response Analysis for Paducah Gaseous Diffusion Plant, Paducah, Kentucky
Abstract
A site response analysis has been conducted for the DOE Paducah Gaseous Diffusion Plant (PGDP) located southwest of Paducah, Kentucky. Synthetic earthquake records corresponding to three return periods were provided. Geotechnical and seismic geophysical data were collected by others and used to create four individual soil columns for the response calculations and one average column used for the sensitivity analysis. The soils primarily consist of continental deposits of sand, silt, and clay overlying arrival deposits. Four soil columns were created with a range of total soil thickness from 322 to 364 ft and all material types represented. The shear wave velocities for soil range from 500 fps near the ground surface to 1,600 fps but generally are between 950 and 1,600 fps. The results of calculations using the one-dimensional wave propagation code SHAKE indicate that ground motions will be amplified at site periods between 0.1 and 2 sec. Natural site periods range from 0.9 to 1.2 sec. The peak free field accelerations are 0.20, 0.27, and 0.36 g for the 500-, 1000- , and 5000-year events, respectively. A sensitivity analysis of various inputs was conducted. Earthquake engineering, Soil amplification, Wave propagation. Site response, Vibration.
