Project Summary

The objective of this research is to further improve a software to accurately measure the total and local volume changes of unsaturated soil specimen during triaxial testing using the conventional triaxial test apparatus for saturated soils without any modification. Specifically, this software will use photographs taken by a commercial digital camera (less than $2000) to achieve measurement accuracies of 5-10 microns (m) in length and 0.02%-0.05% in volume change for a soil specimen of 50mm in diameter and 100mm in height. Laboratory testing procedures will be investigated for the newly developed method.
