Question

Two piles, one a bored cast-in-situ pile and another a precast driven pile, both of same length and diameter are constructed in a loose sand deposit. If the bearing capacity of the bored pile is Q1, and that of the precast driven pile is Q2, then which of the following is correct ?-A-Q1 &gt; Q2B-Q1 = Q2C-Q1 &lt; Q2D-No specific comparison may hold good-A-Q1 &gt; Q2

APTITUDE CRACK · Accepted Answer

The correct option is  A Q1 &gt; Q2 The load carrying capacity of bored cast in situ pile will be much smaller than that of a driven pile in sand. The angle of shearing resistance of the soil is reduced by 30, to account for the loosening of the sand due to the drilling of the hole.
