The void ratio of a soil is 0.55 at an effective normal stress of 140 kPa. The compression index of the soil is 0.25. In order to reduce the void ratio to 0.4, an increase in the magnitude of effective normal stress (in kPa, up to one decimal place) should be
A stratified soil is to be analyzed for stresses. The stratified soil is composed of sand, silt, clay and gravel. The 2.80-m thick gravel underlays the 3.60-m thick clay while the 4.0-m thick sand which overlays the 3.0-m thick silt is overlain by the gravel. Ground water table is at a depth of 8.0-m from the surface of the stratified soil. Soils above GWT are dry. Use the given soil properties below, draw the complete soil profile and perform the following requirements: For sand: Yd = 16.35 kN/m³, Ysat = 19.62 kN/m³ For silt: Yd = 19.35 kN/m³, Ysat = 22.22 kN/m³ For clay: Yd = 17.35 kN/m³, Ysat = 20.82 kN/m³ For gravel: Yd = 18.35 kN/m³, Ysat = 21.52 kN/m³ Note for 1a, 1b, 1c, and 1d that there is no capillary rise in the soils.
