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...

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...

The ground profile of a construction site consists of a 3 m thick layer of sand followed by a 2 m thick layer of clay lying on impervious bedrock. The watertable is at a depth of 2 m below the ground surface. The sand has a dry unit weight of 16 kN/m and a saturated unit weight of 18 kN/m3. The capillary rise in sand is 0.5 m. The clay has a bulk unit weight of 19 kN/m 1. One...

A 5m wide and 10m long rectangular foundation is built on a site where the soil profile consists of 3m of gravel and 4m of clay overlying rigid impermeable rock as shown in Figure 8. The foundation carries a surcharge loading of q=65 kN/m2 Initially the water table is 1 m below the surface of the gravel. The water table rises to the surface of the gravel slowly over a period of time and the surface loading induces an increase...
