    Question # 01 (2+8)

    a) Define the profile of Flexible and Rigid foundation settlement with neat sketches?
    b) A 50 KN/m load was imposed on the 10×15 meter Raft foundation constructed by using M20
    concrete. The top point of the foundation was at +0 meter ground level. The depth of the
    foundation was 2.5 meter. The groundwater table was present at -2.5m. The first layer of soil
    was present at -7m and the second layer of soil was present at -19m. Calculate the total
    settlement of the foundation and draw a complete profile of the settlement.

    Question # 02 (08)
    Calculate the total settlement of the footing for 5 years. (Schmertmann Method), define the settlement
    conditions. (Es=3.5qc)

    Question # 03 (08)
    A group of nine piles arranged in a square pattern with the diameter of the pile is 25 cm, and the length
    of the pile is 10 meters is used as the foundation in soft clay deposit taking the unconfined compressive
    strength of the clay is 120 KN/m2 and the spacing of the pile is 1000 mm c/c. Find the total load capacity
    of the group piles assuming Nc=9, α=0.75, and the factor of safety is 2.5.

    Question # 04 (10)
    A pile of 450mm diameter and 10.5 m length is driven in a sand deposit having C=0, φ=300, γ=16.5
    KN/m2, γsat =18.5 KN/m2, considering critical depth to be 15 times the diameter of the pile, Nq=35,
    k=3.2, φ=200. Calculate the safe load that the pile can carry if the water table is located at a depth of
    2.5 m from the ground level while taking the factor of safety 2.
    Question # 05 (6+8)

    a) In normally consolidated clay stratum of 3-meter thickness has two permeable layers at its top
    and bottom. The liquid limit of the clay is 3.6%, and the clay initial void ratio is 0.82, the
    overburden pressure at the middle of clay is 2 kg/sq.cm. Due to the construction of the new
    building, the pressure increased by 1.5 Kg/sq.cm. Compute the settlement of the building.
    b) The subsoil profile of a proposed site of construction is shown below, a square footing of 2*2
    meter carries a load of 1000 KN and is laid with its base at 1-meter depth below ground surface
    assuming that post-construction settlement in the sand is negligible. Determine the
    consolidation settlement of clay layer on account of construction. There is geological evidence
    that clay is NC, use 2:1 for load dispersion to estimate the stress increase in the clay layer.
