Abstract

The paper demonstrates a novel non-contacting volume change measurement system for triaxial soil testing. The system uses an ultra high accuracy laser displacement sensor that measures water volume changes resulting from the volume change of the specimen during testing. The paper presents the design, working principles, system calibrations, and the validation of the system through comparative measurements of volume changes of soil specimens during triaxial shearing, against results of conventional volume measurement techniques.
