A 1500 kN load was applied on two 20 m long and 500 mm diameter piles that were instrumented for measuring the load variation with depth.

a. The variation of frictional resistance per unit area, f_(z), with depth for the first pile is shown in Figure P12.1a.

Using Eq. (12.9), draw the variation of pile load Q_(z) with depth.

b. The variation of pile load Q_(z) with depth for the second pile is shown in Figure P12.1b. Using Eq. (12.9), draw the variation of frictional resistance per unit area, f(z), with depth.
