Statics Triaxial Test

Triaxial tests is one of the most important experiments in Geotechnical Engineering (Soil Mechanics and Foundations) to determine soil strength parameters in different conditions (UU, CU, CD). In this experiment, based on the type of experiment, first the soil samples under mutual pressure (back pressure) and all-saturated, and after consolidation, while stabilizing the confining stress, vertical stress of soil samples with set speed will be inserted into the sample to be disrupted. The maximum vertical stress for a certain confining stress, axial stress, caused by the diameter of a circle in environment axial stress.

Tests are usually performed with three different confining stresses and thus in the coordinate system "stress shear, stress axis", three circles are obtained that which is draw the best line tangent to these three circles (Mohr's circle), soil strength parameters are determined.

Triaxial testing machine manufacturing in S.M.I Co. in accordance with the international standards such as ASTM designed and built.
