Determination of Soil Properties through Ground Motion Analysis.
Abstract
A method of calculating in situ one dimensional stress-strain soil properties from vertical ground motion is presented. The method relies on the fact that superseismic air blast ground surface loadings produce ground motions that are very nearly vertical and one dimensional in character. Therefore the equations of motion that govern the response are simple and may be integrated to obtain one dimensional stress-strain relations. Thus, results from tests that incorporate superseismic air blast surface loading and sensors to measure vertical motion at various depths in the soil can be used to calculate soil stress-strain properties directly. The method accounts for multiple records at a given depth and features techniques for characterizing response histories and interpolating velocities at depths between those where measurements have been made. As an example, for the DISC HEST Test I event, conducted in Ralston Valley, Nevada as part of the MX development program, the site properties are computed based on the free field data. (Author)
