An investigation into the acoustic emission response of a series of axially stressed dry soil samples is presented in this study. The correlation between acoustic emissions and strain is noted and strongly suggests that acoustic emission monitoring of soil masses may lead to a nondestructive field evaluation technique.
Preliminary insight into the fundamental mechanism of acoustic emissions in dry soils is presented. It is seen that granular soils yield higher accumulated emission counts than fine-grained soils. The summary curves which are presented show this clearly defined trend and can be regarded as laboratory calibration curves for the soils which were tested.
