stress and pore water pressure. 2- A soil profile consists of 10m of sand (Y=20 kN/m') over 3m of organic silt (Y=17KN/m?; 1+eg 0.5,OCR = 1,c, = 8 m?/year)over gravel. Initially, the water table is 2m below the ground surface and hydrostatic condition exists throughout the soil profile. Before constructing a structure on this site, the organic silt is preconsolidated by rapidly lowering the water table by 6m (to 8m below the ground surface) and simultaneously pumping from the gravel layer at such rate that the piezometric level in the gravel is lowered to the bottom of the organic silt. Compute settlement resulting from consolidation of the organic silt if the lowered ground water

2- A soil profile consists of 10m of sand (Y=20 kN/m') over 3m of organic silt (Y=17KN/m?;
0.5,OCR = 1,c, = 8 m?/year)over gravel. Initially, the water table is 2m below the ground
surface and hydrostatic condition exists throughout the soil profile. Before constructing a
structure on this site, the organic silt is preconsolidated by rapidly lowering the water table by
6m (to 8m below the ground surface) and simultaneously pumping from the gravel layer at such
rate that the piezometric level in the gravel is lowered to the bottom of the organic silt.
Compute settlement resulting from consolidation of the organic silt if the lowered ground water
