Abstract

This study presents the development of a simple and cost-effective method for accurately measuring the three-dimensional deformation of soil specimens during triaxial tests. It is possible to derive constitutive parameters using this information in conjunction with other measurements obtained from conventional triaxial tests. The current accuracy of measuring the vertical displacement is shown to be ±0.001 mm. A series of triaxial tests on sand samples with different densities and consolidation histories is used to demonstrate that the image analysis technique can replace local strain instrumentation and bender elements employed in triaxial tests.
