Questions

  1. Q1

    1. a)

      Define Normal consolidation, over consolidation and Pre-consolidation Pressure.

      [6]
    2. b)

      A normally consolidated clay stratum of 5m thickness has two permeable layers at its top and bottom. The liquid limit and the initial void ratio of clay are 40% and 0.85 respectively. While the initial overburden pressure at the middle of clay layers is 300kPa. Due to the construction of a new building, this pressure increases by 150 kPa. Compute the probable primary consolidation settlement (expressed in mm) of the building.

      [6]
    3. c)

      What are the different types of foundation settlements? Explain in detail.

      Also asked:Nov 2024

      [5]

  2. Q2

    1. a)

      Discuss with sketch logarithmic of time fitting method for determination of coefficient of consolidation.

      Also asked:Nov 2025 ·May 2025 ·Nov 2024 ·May 2023 ·Nov 2022

      [6]
    2. b)

      An undisturbed sample of clay 24mm thick consolidated 50% in 20 minutes when tested in the laboratory, with drainage allowed at the top and bottom. The clay layer from which the sample was obtained is 4m tick in the field. How much time will it take place to consolidate 50% with a single drain?

      [6]
    3. c)

      What is contact pressure? Draw contact pressure distribution of a rigid footing on sandy and clayey soil strata.

      [6]
    2. b)

      A circular pile section with 0.35 m diameter and length of 10m penetrates into the clay having c = 50 KN/m 2 and mobilization factor = 0.8. Calculate the safe load with a factor of safety = 2.5. Neglect the bearing resistance.
