A 50-storey concrete building was constructed on a normally consolidated clay layer, which has a layer thickness of 5 m. The building foundation increased the vertical effective stress at midpoint of the clay layer from 70 kPa to 220 kPa (final increase). The coefficient of volume of compressibility (mv) of the clay in this stress range was determined to be 5×10-4 kPa-1 . What would be the long-term settlement of the building foundation due to the primary consolidation of the...

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...

You are evaluating the geotechnical characteristics of a Miami site for a proposed office building. Subsurface investigation showed that the site consists of the following layers: (1) a 5-ft sandy laver with a unit weight of 100 pcf (2) a 10-ft silty sand layer with a saturated unit weight of 115 pcf. (3) a 20-ft saturated clay layer with a unit weight of 118 pef, void ratio of 0.85, and underlain by gravels. The site seemed to have strong potential...

1. An 8-m thick normally consolidated clay layer is doubly drained as shown below. (This means that a very pervious layer compared to the clay exists on top of and under the clay layer) The embankment applied an average vertical stress increase of 100 kPa to the clay layer. The water table is located at the mid depth of the sand layer. Assume the sand above the water table is dry 0 Pore water pressure, u (kPa) 20 40 60...

Hello, I want to know how to calculate the vertical stress induced in each layer if it is a continuous foundation?Example 7.4 The allowable settlement for the proposed continuous footing in Figure 7.9 is 25 mm. Using the classical method, compute its settlement and determine if it satisfies this criterion. Solution P- PD Pt 40 kN/m + 25 kN/m -65 kN/m w/b = (1.2 m)(0.5 m)(23.6 kN/㎡) = 14 kN/m 65 kN/m + 14 kN/m 1.2 m - 0 66...

e3 shows the soil profile (sand-clay-sand) at the site of a warehouse that causes a surface ding of 100 kPa. (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...
