Abstract

The triaxial testing is one of the most common and theoretically sound methods to determine the stress-strainstrength characteristics of soils in the laboratory. The primary function of a triaxial testing system is to apply a threedimensional axisymmetric state of stress in terms of imposed axial and radial stresses as well as longitudinal deformations on a cylindrical soil specimen through all-around chamber fluid pressure and axial load mechanism, respectively. As such, the determination of stress-strength-strain properties of soils through laboratory measurements requires conducting high quality triaxial tests. In this regard, a programming code with userfriendly interfaces for running sophisticated triaxial testing procedures including initial saturation, consolidation and shearing test phases was developed. The created controller software is capable of performing the necessary triaxial test phases including test apparatus set-up, saturation, consolidation and shear testing. As such, the software can consistently control the triaxial system applying either undrained or drained linear stress paths as well as performing isotropically or anisotropically or alternatively one-dimensionally consolidated triaxial tests on soil specimens.
