Refer to the footing in Problem 17.6. For calculating elastic settlement under the footing, it is necessary to estimate the elastic modulus of the foundation soil. Using qc and Eq. (17.33), estimate the variation of elastic modulus with depth for the soil profile shown in Figure 17.15.

Problem 17.6

Refer to Problem 17.5 and Figure 17.15. Suppose a footing (2 m x 2 m) is constructed at a depth of 1.5 m.

a. Estimate the design values for N60 and φ'.

b. What is the net allowable load that the footing can carry? The maximum allowable settlement is 25 mm.

Problem 17.5

Refer to the boring log shown in Figure 17.15. Estimate the average drained friction angle, φ', based on corrected standard penetration number, (N₁)60.
