  • Question
  • Pick up the correct statement from the following:


  • Options
  • A. When water table is above the base of a footing, the dry weight m should be used for soil below water table
  • B. When water table is located somewhat below the base of a footing, the elastic wedge is partly of moist soil and partly of submerged soil, and a suitable reduction factor is used
  • C. When water table is just at the base of the footing, no reduction factor is used
  • D. None of these.

  • Correct Answer
  • When water table is located somewhat below the base of a footing, the elastic wedge is partly of moist soil and partly of submerged soil, and a suitable reduction factor is used
