Running head: GEOTECHNICAL ASSIGNMENT
1A soil sample has a volume of .0.05m3 and a mass of 87.5kg. Given w=15%,Gs=2.68
Determine
a) void ratio
b) porosity
c) Dry unit weight
Moist Unit weight
c) Degree of saturation
Volume=0.05m3
Mass = 87.5kg
W=15%
Gs =2.68
Soln
γ=w/v= 87.5 x 9.81/0.05
γ= 17.2 kN/m3
1+e={Gs(1+w) γw }/γ
1+e={2.68 x (1+0....
