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...

A levee is constructed atop a 3m thick clay layer resting atop a sand layer. During a storm event, the levee retains water and the soil at the bottom of the channel is sand that is hydraulically connected to the sand beneath the clay. Head loss in the sand layer is negligible (i.e., the total head at point A is the same as the total head at point B), and water flows vertically upward through the clay. The water table...

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 water table is at a depth of 2 m below the ground surface. The sand has a dry unit weight of 16 kN/m3 and a saturated unit weight of 18 kN/m3. The capillary rise in the sand is 0.5 m. The clay has a bulk unit weight of 19 kN/m3....

Figure P3 shows the soil profile at a site for a proposed office building. It is expected that the vertical stress at the top of the clay will increase by 150 kPa and at the bottom by 90 kPa. Assurning a linear stress distribution within the clay: (a) Calculate the consolidation settlement. You should divide the clay into five layers, compute the settlement for each layer, and then find the total settlement. Assume G = 2.7 for both sand and...

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...
