The void ratio of the soil with hydraulic gradient 1.2 and specific gravity 1.89 is - 0.25833 ( no unit ) ( negative indicates that the density of the soil is affected when there is increase in load  )

Explanation:

  • Void ratio is defined as the ratio of volume of voids and volume of solids
  • Void ratio is a dimensionless quantity and it is somewhat related to porosity also
  • Hydraulic gradient is a type of driving force
  • Specific Gravity of soil is defined as the ratio of unit weight of the soil mass and unit weight of distilled water at 4°C. Also it is compared to the density of the soil to the density of the distilled water in some cases.

Given Data

Hydraulic gradient of soil = 1.2

Specific gravity of soil = 1.89

To find - the Void ratio of the soil

The formula to find the hydraulic gradient of the soil by using Specific gravity and void ratio is

Hydraulic gradient = (G-1) ÷ ( 1+e) ----------> 1

Where G = Specific gravity of the soil

and e = Void ratio of the soil

The above formula (1) of hydraulic gradient cal be rewritten as

( 1+e ) = ( G-1) ÷ Hydraulic gradient ----------> 2  

Substitute the given values in equation 2

( 1+e ) = (1.89 - 1) ÷ 1.2

( 1+e ) = (0.89 ) ÷ ( 1.2 )

( 1+e ) =  0.74166

e = 0.74166 - 1

e = -0.25833 ( no unit)

Therefore the void ratio of the soil is - 0.25833 ( no unit )
