Stress Path Triaxial Tests System

In geotechnical engineering, the Stress Path Triaxial Tests System is the laboratory test most commonly used to determinate the stress-strain relationship of a soil, in order to obtain reliable soil parameter information for a wide range of geotechnical problems and soil types. With the manual equipment the operator must follow a test step-by-step; adjusting the pressures via the adopted panels and regulators and opening and closing triaxial cell valves. To make the effective stress testing procedure much quicker and easier, a fully automated, computer controlled system is developed. Stress Path Triaxial Tests The laboratory triaxial stress path tests allow the engineering to replicate the changes in stress conditions experienced during excavations, constructions or natural events. Specific stress conditions as compression and extension loadingunloading, k0 consolidation, can be recreated with this type of test. In the automatic systems, the different stages of effective stress and stress path triaxial tests are automatically set up and managed via closed loop servo-pneumatic or servo-hydraulic high technology devices.
