Static Triaxial (stress path)
Description
Soil samples shear strength evaluation is performed by static triaxial apparatus. In this apparatus, all readings and loadings are automatically carried out and saved as an excel file. Stress ratio & velocity at consolidation level is selected by user, so in addition to existence of isotropic condition, all types of anisotropic consolidation can be performed. CU, CD & UU tests are the most well-known tests that can be done by this apparatus according to ASTM D2850 & ASTM D4767. Due to controlling all-around stress, all stress paths can be performed in q-p. In apparatus software 4 successive phases can be defined that each one can match with specific stress path that is applied in drained or undrained condition. Another important feature of this apparatus is that test results are saved as graphs with arbitrary axes during the test is running. This apparatus can be promoted to mechanical wave velocity measurement system and soil suction control system.
