Acoustic Emissions in Medium Plasticity Clayey Silt

Abstract

In spite of recent studies of subaudible acoustic emissions, there has been relatively little work done in the soil mechanics area. This technical note presents a technique of monitoring acoustic emissions of soil under stress. Utilization of such a technique seems to provide an alternate to measuring soil strains, which in the in situ state is quite difficult. The technique may offer a nondestructive testing method for the monitoring of a wide variety of soils under stress.
