g=9.81m/s^2
When it say "preconsolidated under vertical effective stress of
130 kPa", this means that the preconsolidation pressure at the
centre of the clay layer is 130 kPa, NOT that 130 kPa was applied
as a surcharge at the surface.
In the following questions, you do not need to divide the clay layer into multiple layers to calculate the consolidation settlement. Asume the clay to be only one layer q 50 kN/m2 3.0 m dry WT Sand: Ysat 1k -17...

18 A new petroleum storage tank is proposed at an oil refinery to be supported by a 20-meter diameter slab foundation at the ground surface. The structure will produce a uniform load of 110 kN/m2 on the entire slab foundation. A subsurface investigation has revealed the shown soil profile. A series of laboratory tests on representative samples obtained from the clay stratum has resulted in the...

5, A soil element inside a 20° natural soil slope carries total vertical stress (%) of 140 kPa, total horizontal stress (on) of 80 kPa and shear stress (Tvh) of 15 kPa Canticlockwise shear stress on vertical plane). The pore-water pressure (u) inside the element is 30 kPa. The critical state angle of friction of the soil is 30o and its undrained shear strength is 40 kPa.

Problem 4: a) Calculate the total overburden, effective stress and pore pressure distribution for the soil profile below. Neglect the surcharge for this analysis. Draw out all pressure profiles in a neat manner using a ruler. NO sketches and sloppy drawings permitted. b) Calculate the change in pressure if the water table rises to the interface of the clayey/sandy soil layers. You may show your results graphically or report the change in pressures along with the new pressures at the...
