Textbook Problem

For a soil with Gs = 2.7, calculate and plot the variation of dry density (in kg/m3) at w = 8, 12, 16, and 20% and for the degree of saturation at S = 55, 70, 85, and 100%, respectively.

To determine

Calculate and plot the variation of dry density at various water contents and the various degree of saturation.

Explanation

Given information:

The specific gravity of soil Gs is 2.7.

The various water contents of the soil (w) are 8 %, 12 %, 16 %, and 20 %.

The degrees of saturation of the soil (S) are 55 %, 70 %, 85 %, and 100 %.

Calculation:

Determine the dry density of the soil at 8 % water content and 55 5 of degree of saturation using the relation.

ρd=Gsρw1+GswS

Here, ρw is the density of water.

Substitute 2.7 for Gs, 1,000kg/m3 for ρw, 8 % for w, and 55 % for S.

ρd=2.7×1,0001+2.7×(8100)55100=2,7001
