Figure 8.
The top graph plots applied load from 0 to 40 meganewtons against upward movement from 0 to about 230 millimetres. Measured data points increase gradually, then rise sharply beyond about 30 meganewtons, while a modelled curve remains lower and smoother. The lower graph shows applied load from 0 to 70 meganewtons against downward movement to negative 100 millimetres. Measured points remain near zero displacement, while the modelled curve shows increasing downward movement with load, reaching large negative values at higher loads.Plot of fs versus reduced level (lower pile)
Note: This figure presents a comparison between the interpreted shaft friction based on measured strains and the estimated theoretical shaft friction under maximum sustained tested loads of 37.73 MN for lower section of pile
