Cu triaxial test

The shear characteristics are measured under undrained conditions and the sample is assumed to be fully saturated. Measuring the pore pressures in the sample ( sometimes called CUpp) allows . CONSOLIDATED UNDRAINED TRIAXIAL. COMPRESSION TEST FOR UNDISTURBED SOILS. This method determines the angle of internal friction (φ) and cohesion (c) strength parameters of soils by triaxial compression .

CU triaxial test is recommended for all types of soil including cohesive and cohesionless soils.

Pore pressure evolution with in the soil mass can also be studied in CU tests, along .

What are the types of triaxial test ? There are three primary triaxial tests conducted in the laboratory, each allowing the soil response for differing engineering applications to be observed. Consolidated Undrained test ( CU ). To find the shear of the soil by Undrained Triaxial Test. The standard consolidated undrained test is compression test, in which the soil specimen is first consolidated under all round pressure in the triaxial cell before failure is brought about by . The UTEST Triaxial Test System provides automated triaxial compression tests on cylindrical undisturbed and remolded soil samples.

Unconsolidated undrained (UU), consolidated drained (CD) and consolidated undrained ( CU ) compression tests can be automatically run, controlled and reported using this apparatus.

This video is made by student and shared by internet. The video goes through the whole procedure of performing CU test. The most common types of triaxial tests are consolidated drained (CD), consolidated undrained ( CU ) and unconsolidated undrained (UU). The CU and CD triaxial tests take significantly longer to perform and can take weeks or even months to complete.

The CD Triaxial commonly has the longest test duration, as during the shear stage of the test, pore pressure is not allowed to build up, resulting in very low strain rates. CD ( consolidated drained) test: This is similar to CU test except that as deviator stress is increase drainage is permitted. The rate of loading must be slow enough to .
