Question

8.
A circular well has an extemal diameter of 7.5 m and is sunk into a sandy soil to a depth of
20 m below the maximum scour level. The resultant horizontal force is 1800 kN. The well
is subjected to a moment of 36000 KN-m about the maximum scour level due to the lateral
force. Determine whether the well is safe against lateral forces, assuming the well to rotate
(a) about a point above the base (b) about the base. Take unit weight =10 kN/m' and angle
of shearing resistance = 32 degree. Use FOS = 3.
