Question 4 A 10-m-thick layer of stiff saturated clay is underlain by a layer of sand. The sand is under artesian pressure. If H=7.2 m, what would be the minimum height of water h in the cut so that the stability of the saturated clay is not lost? Saturated clay Sand P1840 kg/m 52.^.> 4'コ廳日リ: PD · 30.11.2018

Question 3 An exploratory drill hole was made in a saturated stiff clay. It was observed that the sand layer underlying the clay was under artesian pressure Water in the drill hole rose to a height of H1 above the top of the sand layer. If an open excavation is to be made in the clay, how deep can the excavation proceed before the bottom heaves? we are given H-8 m, H1-4 m, and w: 32% Exploratory drill hole Saturated...

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 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 2 The soil profile at a level site consists of a 3-m thick layer of...
Question 2 The soil profile at a level site consists of a 3-m thick layer of sandy clay, overlaying an 8-m thick layer of loose sand, overlaying stiff gravelly clays that extend to depths greater than 20 m. The water table is at a depth of 2 m and the ground water is initially hydrostatic. The total unit weight of the upper sandy clay, above or below the water table, is 18 kN/m3. The total unit weight of the loose...

Question 4 (20 marks): A 2-m thick normally-consolidated clay soil is resting on impermeable shale rock; a 20-m thick layer of sandy soil is placed on top of the clay to expedite consolidation process. The unit weight of the sand is 15 kN/m3 and the unit weight of the clay is 10 kN/m3. For the clay layer, the initial void ratio is 2.0, the compression index of the clay is Ce 0.40, the recompression index is C, - 0.10, and...

Question 6 It is required to construct a 4 m deep underground carpark in the heart of the city of Melbourne without disturbing the surrounding area. The required excavation for the proposed carpark and also the adjacent ground condition are shown in Figure 6.1. As can be seen from the figure, the adjacent ground consists of a 2 m deep clay deposit, resting on a 2 m thick sand deposit, where stable soil could be found below the sand deposit...
