Q5. A multistorey building with a basement is to be constructed. The top 4 m contains loose silt below which dense sand layer is present upto a great depth. Ground water table is at the ground surface. The foundation consists of the basement slab of 6 m width which will rest on the top of dense sand as shown in figure. For dense sand saturated unit weight is 3 20kN / m3 and bearing capacity factor, Nq = 40, Nγ = 45, for loose silt saturated unit weight = 18kN / m3 , Nq = 15, Nγ = 20 . Effective cohesion is 0. Neglect depth factor average elastic modulus E, and Poisson ratio µ of dense sand is 60 ×102 kN / m2 and 0.3 respectively, using factor of safety = 3. (Take influence factor = 2)
The immediate settlement of foundation is
Answer : Option B
Explaination / Solution:
Si = 552.48 × 6 × [1-(0.3)2]×2/(60×103) = 100.55 mm
