Abstract

The resonant-frequency method of determining the absorption factors characterizing the soil damping properties has been developed for implementation of software programs on computation of dynamic interaction of foundation based constructions. This method is based on processing of amplitude-frequency characteristics of soil samples obtained from the vibro-dynamical tests carried out on the specially constructed installation equipped with the vibro-recording instruments. A set of experiments was performed with sandy and clayey soils at difference humidity, density and stratification depth, based on investigation of forced oscillations of these samples and further processing of the resonance curves within the frames of presentation of the linear theory of viscous elasticity of soils.

Resonant-Frequency Method of Soil Damping Characteristics Determination
