Proportional to the tangent of the angle of shearing resistance.
View all questions of this test
The shear strength of cohesionless soil is reduced as the water pressure inside the pores of the soil mass increases. Experimentally, a series of consolidated drained triaxial tests with back pore water pressure was run on samples of saturated uniform dense sand.
Hence the correct answer is option B.

Explanation:
The shear strength of cohesionless soil is related to the angle of shearing resistance, which is the angle between the horizontal plane and the failure plane of the soil. The relationship between the shear strength and the angle of shearing resistance can be expressed by the Mohr-Coulomb failure criterion, which is given by the equation:
τ = c’ + σn tan(φ)
where τ is the shear stress, c’ is the effective cohesion, σn is the normal stress, and φ is the angle of shearing resistance.
From the above equation, it can be seen that the shear strength is proportional to the tangent of the angle of shearing resistance. This means that as the angle of shearing resistance increases, the shear strength also increases, and vice versa.
Therefore, the correct answer is option B: Proportional to the tangent of the angle of shearing resistance.
Summary:
The shear strength of cohesionless soil is proportional to the tangent of the angle of shearing resistance, which is given by the Mohr-Coulomb failure criterion. As the angle of shearing resistance increases, the shear strength also increases.
