Determination of the Attenuation Factor via Seismoacoustic Studies in Wells to Estimate the Distribution of Heterogeneities in Artificial Soils

摘要

Quality control by hidden works in artificial soils is a relevant problem in construction engineering. Seismoacoustic methods are widely used for its solution. In this work, seismoacoustic well logs in artificial soils manufactured by the jet grouting technology were processes to obtain additional data on the distribution of heterogeneities in an artificial soil. The spectral ratio and frequency shift methods were used to estimate the attenuation factor.
