A site consists of 15 m of very weak soil, underlain by good-quality rock where the uniaxial compressive strength σc is 40 MN/m2 . It is proposed to install a 650-mm-diameter rock-socketed pile with 1.5- m-long socket into the rock. The compressive strength of concrete is 35 MN/m2 . With factor of safety of 3.0, what would be the maximum load that can be allowed on top of the pile? Use Rowe and Armitage (1987) values of c and d in Table 13.9 for computing qb.
