The paper presents an attempt to evaluate the feasibility of predicting the value of the coefficient of the earth pressure at rest Ko of natural soil deposits on the basis of the measured velocities of the seismic shear waves. The experimental data presented were obtained from seismic tests performed in a calibration chamber on laboratory prepared specimens of seven granular materials, with grades ranging from fine sand to gravelly sand. The relationship between Ko and the shear wave velocity established using the calibration chamber results was used successfully to predict Ko at two well-documented sites for which both cross-hole seismic and seismic piezocone penetration test results are available.

Abstract
The paper presents an attempt to evaluate the feasibility of predicting the value of the coefficient of the earth pressure at rest Ko of natural soil deposits on the basis of the measured velocities of the seismic shear waves. The experimental data presented were obtained from seismic tests performed in a calibration chamber on laboratory prepared specimens of seven granular materials, with grades ranging from fine sand to gravelly sand. The relationship between Ko and the shear wave velocity established using the calibration chamber results was used successfully to predict Ko at two well-documented sites for which both cross-hole seismic and seismic piezocone penetration test results are available.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
