Textbook Problem

The degree of saturation of a soil is 55% and the moist unit weight is 106 lb/ft3. When the moist unit weight increased to 114 lb/ft3, the degree of saturation increased to 82.2%. Determine:

a. Gs

b. Void ratio

(a)

To determine

Calculate the specific gravity of soil solids.

Explanation

Given information:

The degree of saturation (S1) is 55%.

The moist unit weight of soil (γ1) is 106lb/ft3.

The degree of saturation (S2) is 82.2%.

The moist unit weight of soil (γ2) is 114lb/ft3.

Calculation:

Consider the unit weight of water (γw) is 62.4lb/ft3.

Calculate the specific gravity of soil solids (Gs) using the relation.

γ=(Gs+Se)γw1+e (1)

For 55% of saturation:

Substitute 106lb/ft3 for γ, 62.4lb/ft3 for γw, and 55% for S in Equation (1).

106=(Gs+55100e)×62.41+e106+106e=(Gs+0

(b)

To determine

Calculate the void ratio of the soil.
