Use the data from Prob. 9.11 and Fig. 9.38 and assume a level-ground site. A proposed building will have a deep foundation system consisting of piles that are driven into the Flysh claystone. Assuming that the piles are widely spaced and do not increase the liquefaction resistance of the soil, calculate the differential movement between the building and adjacent ground.
