Question 5 (Effective Stress & Consolidation) Figure 05 shows the soil profile of a construction site. The water table is at the ground surface. Saturated unit weight of the sand is 18.8kN/m' and that of the clay is 19.6kN/m. Assume permeability of the clay is very low and unit weight of water is 10kN/m'. Water Table Sand 5m Clay 6m Figure 05 a) Determine the vertical total stress, pore water pressure, and vertical effective stress at the mid-height of the...
A proposed embankment fill requires 5000 m3 of compacted soil. The void ratio of the compacted fill is specified as 0.75. Soil can be transported from one of the four borrow pits as shown in the table below. The void ratio, specific gravity of soil solids, and the cost per cubic meter for moving the soil to the proposed construction site are provided in the table. a. Determine the volume of each borrow pit soil required to meet the specification...
TOTAL CONSOLIDATION SETLEMENT Example 1: if the initial void ratio of a clay is e. = 0.9 at initial pressure o =95.8 kN/m, and the compression index of that soil is equal (Cc)=0.052, H=4 m thick, L.L.=42 %. If the clay layer is loaded with infinite load of Ao=287.5 kN/m?, calculate the amount of total settlement of the clay. Сс Se = H .log 1+e, 0 0
For a normally consolidated clay layer, given: Thickness-3.7 m Void ratio- 0.82 Liquid limit 42 Average effective stress on the clay layer 110 kN/m2 How much consolidation settlement would the clay undergo if the average effective stress on the clay layer is increased to 155 kN/m as the result of the construction of a foundation?

Use a Mohr circle that touches the failure enve psf and 32 deg. acting on it. What is the shear strength of the soil on that plane? of 2000 psf to estimate the values of σ, and σ, at a state of shear failure 2000 psf lope at...
Describe what you learned this week as to how stress can impact one's health. Describe a time in your life (or in the life of another individual) when stress led to illness. How did you/they overcome the stress and illness? What are some strategies you use today to help you manage stress.

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 Fiqure 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...
