    Sheer failure and settlement determines allowable bearing capacity.

  1. The following two statements are made with reference to the calculation of net bearing capacity of a footing in pure clay soil (f = 0) using Terzaghi’s bearing capacity theory. Identify if they are TRUE or FALSE.
    I. Increase in footing width will result in increase in bearing capacity.
    II. Increase in depth of foundation will result in higher bearing capacity.

    Net bearing capacity of clay is independent of width and depth of footing. Therefore both statements are FALSE.

    Correct Option: B

    Net bearing capacity of clay is independent of width and depth of footing. Therefore both statements are FALSE.
