1. (25 points) The soil profile at a site consists of a layer of fine sand 5 m thick above a layer of clay 4 m thick. Below the clay is a layer of impermeable rock. The groundwater table was observed at 2 m below ground level. The unit weight of the sand above and below the water table is 20 KN/m'. The water content of the clay is 25% and its dry unit weight is 15 KN/m'. The compression...

[Problems 1-4] The soil profile at a site for a proposed office building consists of a layer of fine sand 10.4 m thick above a layer of soft, normally consolidated clay 2 m thick. Below the soft clay is a deposit of coarse sand. The groundwater table was observed at 3 m below ground level. The void ratio of the sand is 0.76, and the water content of the clay is 43%. The building will impose a 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...

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...

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...
