The direct shear test suffers from the following disadvantage:
Drain condition cannot be controlled
Pore water pressure cannot be measured
Shear stress on the failure plane is not uniform.
The area under the shear and vertical loads does not remain constant throughout the test
All the above.
Answer: Option

-> The failure plane is always horizontal in the test, and this may not be the weakest plane in the sample. Failure of the soil occurs progressively from the edges towards the centre of the sample.

-> There is no provision for measuring pore water pressure in the shear box and so it is not possible to determine effective stresses from undrained tests.

->The shear box apparatus cannot give reliable undrained strengths because it is impossible to prevent localised drainage away from the shear plane.
