AE & JE CE Quiz Shear Strength of Soil

Which one of the following test on a saturated clay soil gives the unique effective stress Mohr circle?

Given that the effective angle of internal friction of the soil is 10⁰, the angle between the failure plane and the major principle plane will be:

The angle of repose of a soil is the maximum angle which the outer face of the soil mass makes

A soil has an angle of shearing of 30° and cohesion of 35 kN/m². If the specimen of this soil is subjected to a tri-axial compression test, then the value of lateral pressure in the cell for failure to occur at total stress of 300 kN/m² will be

Why triaxial test is preferred over direct shear test ?

For a tri-axial shear test conducted on a sand specimen at a confining pressure of 100kN/m² under drained conditions, resulted in a deviator stress (s₁–s₃) at failure of 100kN/m². The angle of shearing resistance of the soil would be

During the first stage of triaxial test when the cell pressure is increased from 0.15 N/mm² to 0.28 N/mm², the pore pressure increases from 0.07 N/mm² to 0.15 N/mm². What is the value of the skempton’s pore pressure parameter B?
