... tons) of which 1200 tons (1090 metric tons) were allowed for negative skin friction loads. Deformation gages were installed at various levels in two of the piles to measure the axial compression as the negative skin friction accumulated. Contrary to expectations, hydration caused the piles to lengthen...
