5. A group of 15 piles of 450mm diameter each are arranged in 3 x 5 pattern to a depth of 9m in a 16m thick medium stiff clay. The average unconfined compressive strength of clay is found to be 120 kPa. The adhesion factor between concrete and in-situ clay is found to be 0.58. Estimate the safe load carrying capacity of the pile group with an overall factor of safety of 3.0, if the center to center spacing of piles is 0.9m

6. Write a note on “Dynamic formulae” and comment on their validity

7. A R.C.C. pile of size 30cm X 30cm and 10m long is driven into coarse sand with unit weight of 16kN/m3 and angle of internal friction of 310. What is the allowable load on the pile? For φ=310, N q= 16 and N γ = 14.Take K=1.0 and factor of safety of 3.0.

8. What is negative skin friction in piles? Explain.

9. Sketch an open well foundation and show the various components. Explain the functions of various components

10. Explain the “Pile Load Tests” in detail


Unit 8:

1. Describe various types of Caisson Foundations and comment on their suitability.

2 Explain in detail the procedure of “Sinking of Well foundations”.

3. With the help of a neat sketch, show the components of an “Open Caisson” and explain the function of each component.

4. With the help of neat sketch, show the components of a “Pneumatic Caisson” and explain their function. Also explain the procedure of sinking of “Pneumatic Caissons”.
