needed, vertical wick drains inserted between the preloaded piers can accelerate con-
solidation. The end result is a pier-soil composite with enhanced stiffness and strength
to support the foundation loads within a tolerable degree of settlement.
This process can be viewed as a cavity expansion problem. Figure 6.34 shows the
construction of geopiers.
