The time for 50% consolidation of a 25 mm thick clay specimen (drained at top and bottom) in the laboratory is 150 sec. How long (in days) will it take for a 3 m thick layer of the same clay in the field under the same pressure increment to reach 75% consolidation? There is an impermeable shale layer at the bottom of the clay layer in the field I. 2. Use Figure 1 for the following Compute the vertical effective...

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...

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...

3) A geotechnical analysis of a building site reveals that 5 m thick clay layer is underlain by impervious rock. A 50 mm thick sample of the soil is tested in a double drainage apparatus. During the test, 50% of the ultimate consolidation occurs in 30 min. What is the coefficient of consolidation? (b) How long will it take for the 5 m thick layer to achieve 90% of its ultimate primary consolidation?| (a)

A new foundation will be built on a 2.5m thick clay layer. The current effective stress in the middle of the clay layer was found to be 200 kPa. During construction, the foundation area will be heavily loaded with the structure and equipment so that effective stress at the middle of the clay layer will be increased to 800 kPa. After construction is completed, which will take 5 years, the equipment will be removed and the final effective stress in...
