Determine: a) Specific Gravity b) void ratio Can you please elaborate, Thankyou. What happened to that part when solving the equation 1 and 2 and how did you get the answer
The soil profile at a site consists of 2 m of sand at the groundlevel, underlain by 6 m of clay, followed by a very stiff claystratum that can be assumed to be impervious and incompressible.The water table is at 1.5 m below the ground level. Themoist and saturated unit weights of the sand are 17.0 kN/m3and 18.5 kN/m3, respectively. The clay has an initial void ratioof 0.810, saturated unit weight of 19.0 kN/m3, and coefficientof consolidation of 0.0014 cm2/s.a.
