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)

Question 4 (20 marks): A 2-m thick normally-consolidated clay soil is resting on impermeable shale rock; a 20-m thick layer of sandy soil is placed on top of the clay to expedite consolidation process. The unit weight of the sand is 15 kN/m3 and the unit weight of the clay is 10 kN/m3. For the clay layer, the initial void ratio is 2.0, the compression index of the clay is Ce 0.40, the recompression index is C, - 0.10, and...

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....

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 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...

Example 2:3 The soil profile at a site consists of a 3 m thick sand layer (Ybulk -16.5 kN/m3 sat18.5 kN/m3) underlain by a 6 m thick clay layer (w-27%, Gs-270, m,-0.31 MPa", cv-2.6 m2/year), which is underlain by a gravel layer. A 3 m compacted fill with a unit weight of 20 kN/m3 is to be placed at ground level. a. What would be the final consolidation settlement? b. How long will it take for 50 mm of consolidation...

help with problems 1 & 2 please and explain
Problem 1 A deposit of Swedish clay is 15 m thick drained at both top and bottom. The coefficient of consolidation for the clay layer was estimated to be 1 x 10 cm/sec from laboratory test. The ultimate consolidation settlement (Sc) was calculated under the applied load in the field and was found 80 cm. Find the following: a) How long would it take for settlement of 40 cm and 70...

Problem 1: Fibre optics (2 points) Figure 1: Sketches of the geometry of an optical fibre A long cylinder of dielectric material can guide light via total internal reflection. This idea dates back to the 1870s and forms the basis of the modern fibre optics communication technology. As long as the diameter of these fibres is large compared to the wavelength of the infalling light, its wave nature is negligible and we can use Geometric Optics to study the propagation...

1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...
