Problem 3. (20 points) The analysis of liquefaction of the saturated sand at a particular depth in a soil profile gives a factor of safety of 0.8. That is, the sand is expected to liquefy if the design earthquake occurs. At a particular depth in the liquefiable soil the blow count from the Japanese apparatus (which is different from the N value we get from our SPT) is N₁ = 13. The liquefiable sand layer is 8 m thick. We assume that the strains estimated for this depth are representative of the entire layer. After the excess pore generated by the earthquake dissipates, what is the settlement due to compression of this layer? Give your answer in mm.
