Question

for a triaxial shear test conducted on a sand specimen at a confining pressure of 200 kn/m2 under drained conditions resulted in a deviator stress (??1 - ??3) at failure of 200 kn/m2. the angle of shearing resistance of the soil would be

Answer 1

The triaxial shear test is one of the most reliable methods available for determining shear strength parameters.

It is used widely for research and conventional testing.

The test consists of two-stage the first one is isotropic loading where the specimen is subjected to a confining pressure by compression of the fluid in the chamber.

The second stage is shearing to cause shear failure in the specimen, where axial stress is applied through a vertical loading ram.
