摘要: Dynamic properties of solid waste are needed to reliably evaluate the seismic response landfills. A testing method for investigating dynamic in situ has been implemented at various The field is primarily aimed evaluating shear wave and compression velocities small strains as well modulus reduction versus shearing strain relationship waste. In this study, nonlinearity was successfully evaluated ranging from 10–4 0.2 %. between investigated by applying horizontal loads applied a mobile shaker surface staged-loading sequence. measured with buried array three-component geophones. also permitted assessment effect confining stress variability on Load-settlement measurements unit weight were made. Testing equipment, setup, procedure, data analysis, examples test results presented.
