In a site reclamation project, 2.5 m of graded fill (y=22KN/m³) were laid in the compacted layers over an existing layer of silty clay (y= 18 KN/m³) which has 3 m thick. This was underlain by a 2 m thick layer of gravel (y=20 KN/m³). Assuming the water table remains at the surface of silty clay draw the effective stress profiles for case after the fill has been placed.

A silty clay was brought to the lab for DST testing. Three drained tests were conducted, with effective stresses = 20, 30 and 40 kPa. The critical state shear stresses measured were 29.5, 36.2, and 43 kPa, respectively. Calculate the effective friction angle of the silty clay. Express your answer in degrees
A 5 m thick saturated soil stratum has a compression index of 0.25 and coefficient of permeability 3.2*10^(-3) mm/sec. If the void ratio is 1.9 at vertical stress of 0.15 N/ mm^2, compute the void ratio when the vertical stress is increased to 0.2 N/mm^2. Also calculate settlement due to above stress increase and time required for 50% consolidation?

Q3: Answer with false or true then correct the wrong one. 1- Up to 50 % liquid limits the soils behaves as a high plastic soil. 2- When a soil dried to shrinkage limit, it is easy to crack under pressure and considered as partially saturated. 3- The kaolinite clay formation is consisting of one silica tetrahedral sheets stacked by two aluminum octahedron sheets. 4- The piping phenomena occur at maximum effective stress value and minimum pore water pressure. 5- The water level above the ground level affects the value of the effective stresses at a certain point below the ground level. 6- Illite clay is less stable compared with montmorillonite clay due the secondary bond of potassium. 7- The summation of equipotential drops represents the difference between upstream water level and the elevation of the datum. 8- Theoretically, the plastic limit value must be less than the value of liquid limit for the same soil. 9- The specific gravity has a unit of g/cm-3. 10- The specific surface area…

In a reclamation project, the middle of a clay layer is under an initial effective vertical stress of 200 kPa and initial void The clay is ratio (eo) of 0.90. overconsolidated with OCR of 1.4, compression index of 0.34 and expansion index of 0.07. With an applied load of 299 kPa, what will be the final void ratio (e1) for the clay?
Refer to Figure below. Estimate the primary consolidation settlement in the clay layer. Given: Δσ = 150 kN/m2; H1 = 3 m; H2 = 4 m; and H3= 5 m. Soil characteristics are as follows: • Sand: γdry = 15 kN/m3, γsat = 19 kN/m3 • Clay: LL = 65; e = 0.65; γsat = 18 kN/m3; ; Cs =1/6cc σʹc = 200 kN/m2
