Test: Rankine's Theory of Bearing Capacity - Question 3

### The bearing capacity of cohesion-less soil at the ground surface is __________

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 3

According to Rankine’s equation bearing capacity of cohesion less soil is zero at the ground surface.

Test: Rankine's Theory of Bearing Capacity - Question 4

The safe bearing capacity can also be referred as _________

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 4

Sometimes, the safe bearing capacity is also referred to as the ultimate bearing capacity qf divided by a factor of safety F.

Test: Rankine's Theory of Bearing Capacity - Question 5

The ultimate bearing capacity and the net ultimate capacity are connected by the relation ____________

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 5

The ultimate bearing capacity qf and the net ultimate capacity are connected by the following relation:
qf = qnf + σ̅ (or) qf = qf – σ̅
where σ̅ is the effective surcharge at the base level of the foundation.

Test: Rankine's Theory of Bearing Capacity - Question 6

The gross pressure intensity (q) of a structure is ___________

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 6

The gross pressure intensity q is the total pressure at the base of the footing due to the weight of the superstructure.

Test: Rankine's Theory of Bearing Capacity - Question 7

The net safe bearing capacity is defined by which of the following equation?

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 7

The net safe bearing capacity is the net ultimate bearing capacity divided by a factor of safety F i.e., qns = qnf/F.

Test: Rankine's Theory of Bearing Capacity - Question 8

Rankine considered the first soil element (element 1) at ___________

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 8

Rankine considered the equilibrium of two soil elements, The first one immediately below the foundation (element 1).

Test: Rankine's Theory of Bearing Capacity - Question 9

When a state of equilibrium is reached under the footing?

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 9

When the load on footing increases, and approaches a value qf, a state of plastic equilibrium is reached under the footing.

Test: Rankine's Theory of Bearing Capacity - Question 10

During the state of shear failure, which of the following principal stress relationship exist?

Detailed Solution for Test: Rankine's Theory of Bearing Capacity - Question 10

During the state of shear failure (plastic equilibrium), the following principal stress relationship exists σ1 = σ3 tan2 α + 2c tan α
for cohesion-less soil,σ1 = σ3 tan2 α.
