Question

The width and depth of a footing are 2 and 1.5 m respectively. The water table at the site is at a depth of 3 m below the ground level. The water table correction factor for the calculation of the bearing capacity of soil is

• A.
  0.875
• B. 1.000
• C.
  0.925
• D. 0.500

Answer 1

The correct option is A

0.875

Water table correction factor $$R_w^{\prime }=0.5(1+\frac{D_w^{\prime }}{B})\ngtr 1$$
Where
$$D_w^{\prime }=\text{depth of water table measured from the base of footing}$$ $$R_w^{\prime }=0.5(1+\frac{1.5}{2})$$$$=0.875<1$$$$=0.875$$
