The construction of a new embankment induces a uniform
load of 18kN/m^2 on the top of a 12 meter thick layer of saturated
clay, whose characteristics are as follows:
bulk unit weight γ=16kN/m^3
intial void ratio is 1.8
compression index Cc= 0.7
the water table is at the initial ground level top of
the clay laye. Assuming the clay is normally consolidated.
a) Estimate the settlement of the clay layer after the realization
of the embankment.
b) Compare results obtained by dividing the clay layer in 3
sub-layers.

relatively 5E m2/sec The 2. A new, wide highway embankment is planned deposit of doubly-drained, saturated clay soil with c settlement analysis of the 10 m thick clay layer yielded consolidation settlement of 800 mm for the new embankment loading. Determine and plot the settlement of the clay layer (as measured at the ground surface) at 0, 0.49, 3.12, 6.39, 13.44, and 18.44 years. recent across a an estimated relatively 5E m2/sec The 2.

geotechnical engineering The soil profile at a site consists of a clay layer 10 m thick, sandwich between two sand layers. The top sand layer has a density of 1.9 Mg/m² and is 5 m thick. Below this layer is a 10 m thick clay layer with a saturated density of 1.8 Mg/m' and a saturated water content 42%. The deeper sand layer has a saturated density of 1.9 Mg/m² and extend to the depth investigated at the site. The...
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...
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...
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...
Question 5 (20 marks) A I-m thick, c applied on the top surface of the clay using Sheepsfoot rollers t Ily-saturated clay is resting on a dry sand when a uniform load of 200 kN/m2 is expedite consolidation process For the saturated clay layer, the initial void ratio of 5.0, specific gravity of 2.65, pre-consolidation ression index of 0.2, and the stress of 20 kN/m2: the compression index of 0.5, the recomp coefficient of consolidation of 0.001 cm2 s" a)...
Please, show step by step and clearly. problem 9.17, (Use 3 equally divided sub-layers for the 15 m clay layer). thanks please, resolve question 9.17 (Use 3 equally divided sub-layers for the 15 m clay layer) 9.16 The soil profile and the loading condition are given in the followin n) figure. Total new footing stress including the foundation at z 2 is 400 kN/m2. The soil profile has a rather thick clay layer (15 so that the layer should be...
Question 2 [Marks: 15 +10=25] 200kPa of construction stress was applied on top of the soil layers as shown in the figure below. (1) Calculate the settlement in the clay layer due to the construction (minimum of 2 sub layers is to be used). (W) If the soil went through 90% average degree of consolidation in 1 year, calculate the coefficient of consolidation (C.). 个 Sand Y = 20kN/m 4m Water table Clay (over consolidated) y = 16kN/m 100 4m...
