Chapter 3, Problem 3.10QPP

A 3 ft square footing carries a sustained load of 10 k. It is placed on the surface of a 30 ft thick saturated over consolidated clay underlain by dense sand. Based on laboratory tests, the clay can be adequately modeled using the e-log-p method. The laboratory tests provide the following compressibility information for the clay: $\begin{array}{l}\gamma =123{\text{lb/ft}}^{\text{3}}\\ \frac{C_c}{1+e_0}=0.06\\ \frac{C_r}{1+e_0}=0.002\\ {\sigma }_m^{\text{'}}=900{\text{lb/ft}}^{\text{2}}\end{array}$

The groundwater table is located at the ground surface. Compute the settlement of the footing.
