A FURTHER STUDY OF STRESS-WAVE TRANSMISSION

Abstract

The development of equipment and instrumentation and the establishment of confidence levels in equipment and instrumentation for conducting stress-wave propagation studies are discussed. Then of a free-field soil stress gauge suitable for the stress-wave propagation studies and the evaluation tests performed to establish a confidence level for the gauge are reported. A description is also included of the sample containment system in which the confining pressure is generated by the lateral stress and strain in the soil. This system approaches the completely confined condition with a minimum of side-wall friction effect. Results from preliminary stress wave propagation tests employing a controlled stress pulse of a shape that can be used to identify changes taking place in the soil as a result of the characteristics of the soil are delineated.
