Question

A pile group of four identical piles are connected to a rigid pile cap. Diameter of each pile is 0.8 m and a load test gave a settlement of 15 mm under a load of 500 kN. Poisson's ratio of the soil is 0.5 and it can be assumed that the rigid stratum lies far below the base of the piles. Pile stiffness factor is 2000. The spacing between piles is 1.5 m and the embedded depth is 8 m. What is the settlement of the pile group under a load of 2 MN?

A) 200mm

B) 140mm

C) 80mm

D) 40mm
