Figure 5-1. Groups of deep foundations
h. Interaction effects. Deep foundations where spacings
cutoff. Steel pile cutoffs should be considered in the analysis as
between individual piles are less than six times the pile width B
not totally impervious. Flexible steel sheet piles should cause
negligible load to be transferred to the soil. Rigid cutoffs, such
cause interaction effects between adjacent piles from
as a concrete cutoff, will transfer the unbalanced earth and water
pressures to the structure and shall be accounted for in the
analysis of the pile group.
