Problem 2. [2596] Figure 2 shows a soil profile. The uniformly distributed load on the ground surface is (1) Estimate the primary consolidation settlement of the clay layer due to the application of Ap. (2) If the clay layer is preconsolidated and the average preconsolidation pressure is 80 kPa, what will be the expected primary consolidation settlement if the recompression index is C 0.2 x Cc? p 87 kPa 1 m Dry Sand Sand: Saturated Sand Dry Unit weight: 14.6...
Problem 7 The soil profile at a site consists of a top 4 m layer of dense sand followed by 2 m of clay, which is underlain by a stiff stratum. The water table is at 2 m below the ground level. The following data was obtained from a consolidation test on an undisturbed sample obtained from the middle of the clay layer: water content 5 36%, specific gravity of the clay grains = 2.72, compression index = 0.72, recompression...
Two undisturbed clay samples were taken from the middle of the overconsolidated and normally consolidated clay layers in the soil profile shown. The water table is at the top of the overconsolidated clay layer. Consolidation tests were carried out on the two samples and the results are summarized in the table below. Assume that the bulk, dry, and saturated unit weights of the sand are 16 kN/m3, 16 kN/m3 and 19 kN/m3, respectively. The specific gravity of the clay soil...
For the soil profile shown below, calculate the final settlement due to the placement of the sand fill. Estimate the excess pore pressure at a depth of 1.5 m into the third clay layer 1.5 years after the fill is placed. Assume the coefficient of consolidation is Cv = 1.8 m2/yr. Fill y = 16.0 kN/m² (3m thick) Clay 1 (3m thick) Sand (0.5m thick) Clay 2 (2m thick) Sand (0.5m thick) Clay 3 (4m thick) Sand (0.5m thick) eo...
please show step by step (also show how to find the vertical stress increase) 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...

(pw= 1000 kg/m; g 9.81 m/s2) on 4 (25 marks) A clay sample was cored at 7 m depth (middle of the clay layer). Based on laboratory test data, it was found that the clay was over-consolidated with OCR = 2.5 (before applying surface loading), compression index Ce 0.44 and recompression index C. = 0.1. The consolidation coefficient of clay...

3) At a construction site, a site investigation has been carried out. At ground level (-1 m NAP) a clay layer with a thickness of 4 m is found (y = 16 kN/m”, k = 2.0x10-12 m/s, Cp = 15), followed by a sand layer of 6 m thickness (y = 20 kN/m², k = 5.0x10-7 m/s), another clay layer of 4m thickness (y = 18 kN/m3, k = 4.5x10-11 m/s, Cp = 25), and finally another sand layer (y...
