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.

PROBLEM The results of two triaxial shear tests on CH clay whose plasticity index is 50, unit weight 20kN/m³ are given below. Determine the shearing resistance of this clay at a depth of 15m by assuming (a) the clay is normally loaded(NL); and then (b) clay is overconsolidated(oC) TEST No 1 2 CELL PRESSURE(03)kPa 100 200 DEVIATOR STRESS (oa) 120 145
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…

6 m thick silty sand filling was laid on a 12 m thick compressible clay layer with controlled compression technique. Under this clay layer, there is a 4 m thick pebbly sand layer. Assuming that the settlement of the embankment and gravel-sand layer is insignificant compared to the settlement of the clay layer, calculate the consolidation settlement of the clay layer and when 50% of this settlement will occur. NOTE: You can make the settlement calculation as a single layer calculation.
1. A soil profile is shown in the figure. A uniformly distributed load of 75kPa is applied at the ground surface. The clay is normally consolidated. Compute the secondary settlement 8 years after the completion of primary consolidation. Time for completion of primary settlement is 2 years. Assume secondary compression index = 0.025
