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. Draw completely the soil profile. 1a. Effective stress at the middle of the sand 1b. Effective stress at the middle of the silt 1c.

Question
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. Draw completely the soil profile.
1a. Effective stress at the middle of the sand
1b. Effective stress at the middle of the silt
1c. Effective stress at the middle of the clay
1d. effective stress at the middle of the gravel
