those buildings founded on solid rock are least likely to experience
earthquake-induced differential settlement. However, buildings on soil could be subjected
to many different types of earthquake-induced settlement. This chapter deals with
only settlement of soil for a level-ground surface condition. The types of earthquakeinduced
settlement discussed in this chapter are as follows:
 Settlement versus the factor of safety against liquefaction (Sec. 7.2): This section discusses
two methods that can be used to estimate the ground surface settlement for various
values of the factor of safety against liquefaction (FS). If FS is less than or equal to
1.0, then liquefaction will occur, and the settlement occurs as water flows from the soil
in response to the earthquake-induced excess pore water pressures. Even for FS greater
than 1.0, there could still be the generation of excess pore water pressures and hence settlement
of the soil. However, the amount of settlement will be much greater for the liquefaction
condition compared to the nonliquefied state.
