In a direct shear box test, the plane of shear failure is predetermined.

Better control is achieved on the drainage of the soil in a triaxial compression test.

Stress distribution on the failure plane in the case of triaxial compression test is uniform.

Unconfined compression test can be carried out on all types of soils.
