Figure 5.
The top plot shows strain in microstrain on the horizontal axis from 0 to 1000 and elevation from about negative 1 to negative 79 metres A H D. Red circular markers labelled upper pile show low strain near the surface and increasing strain with depth, reaching higher values below negative 60 metres. The lower plot shows blue markers labelled lower pile between about negative 79.6 and negative 85.6 metres A H D. Strain increases with depth, and a sloping reference line and horizontal line indicate interpreted trends and layer boundaries.Plot of strain versus reduced level (upper pile)
Note: This figure presents the measured strains under maximum sustained tested loads of 34.51 MN for upper section of pile
