Answer #1

1. Triaxial compression test is used to find shear strength of soil at different driange conditions controlled with the help of triaxial cell.

The following are the advantages of triaxial compression test over direct shear test :-

a. )The stress to strain change behaviour is completely determined.

b.)undrained and drained conditions maintained and tests carried out in that conditions.

c.) Various combinations of principal deviation stress and axial stressess can be applied

d.) The soil undergo uniform stresses and strains throughout the soil.

e) In undrained condition the pore water pressure is measured.
