SECTION-B
11. What is the basic difference between a drilled pier and a caisson? What are the conditions
in which a drilled pier is more suitable than a caisson?
12. How would you estimate the load carrying capacity of drilled pier in sand?
13. Describe any two methods for the construction of drilled piers.
14. What are different types of earth pressure? Give examples.
15. What are the assumptions in Coulomb's theory?
SECTION-C
16. Determine the ultimate bearing capacity of a strip footing, 1.20 m wide, and having the
depth of foundation of 1.0 m. Use Terzaghi's theory and assume general shear failure.
Take ' = 35?, = 18 kN/m3 and c' = 15 kN/m2.
17. Describe the procedure for the design of a strap footing.
18. How would you fix the depth of foundation? Discuss Rankine's formula for the minimum
depth.
NOTE : Disclosure of identity by writing mobile number or making passing request on any
page of Answer sheet will lead to UMC case against the Student.
