A cohesionless soil having an angle of shearing resistant of ϕ, is standing at a slope angle of i. The factor of safety of the slope is:
Detailed Solution: Question 1
A finite slope of cohesion less soil is safe so long as
Detailed Solution: Question 2
from which
In the friction circle method the radius of the friction circle is given by
Detailed Solution: Question 3
Taylor's stability number is equal to
where c = unit cohesion, Fc = factor of safety with respect to cohesion, γ = unit weight of soil, Hc = critical height, H = actual height
where c = unit cohesion, Fc = factor of safety with respect to cohesion, γ = unit weight of soil, Hc = critical height, H = actual height
Detailed Solution: Question 4
If the unit weight of soil is 20 kN/m3 cohesion is 15 kN/m2, factor of safety is 1.5 and the stability number is 0.05, the safe maximum height of the slope is
Detailed Solution: Question 5
An infinite soil slope with an inclination of 35° is subjected to seepage parallel to its surface. The soil is assumed cohesionless (c′ = 0 kN/m2) with a friction angle (φ′) of 30°. At a factor of safety of 1.5 with respect to shear strength, the mobilized friction angle (φm) is
Detailed Solution: Question 6
List-I given below gives the possible types of failure for a finite soil slope and List-II gives the reasons for these different types of failure. Match the items in List-I with the items in List-II and select the correct answer from the codes given below the lists:
List-I
A. Base failure
B. Face failure
C. Toe failure
List-II
1. Soils above and below the toe have same strength
2. Soil above the toe is comparatively weaker
3. Soil above the toe is comparatively stronger
List-I

Detailed Solution: Question 7
Taylor’s stability number curves are used for the analysis of stability of slopes. The angle of shearing resistance used in the chart is the:
Detailed Solution: Question 8
An excavation was made at a slope angle of 54° in homogeneous clay. When the depth of excavation reached 8m, a slip occurred. The slip surface was likely to have passed through a point:
Detailed Solution: Question 9
