Figure 14.
The four-panel labelled A, B, C, and D depicts cone resistance q c in megapascal on the horizontal axis and penetration in metres on the vertical axis. Panel A shows Loose soil at Site D with D r equals 0.26. Panel B shows medium-dense soil at Site D with D r equals 0.6. Panel C shows Dense soil at Site D with D r equals 0.77. Panel D shows Dense to very dense soil at Site E with D r values of 0.7, 0.8, and 0.9. Each panel includes a global curve labelled q c global and d c equals 3.57 centimetres, showing increasing resistance with depth and density.Offshore CPTs from the North Sea illustrating shallow depth interpretation using the updated global model: (a) loose sand (Dr ≈ 0.26), (b) medium dense sand (Dr ≈ 0.60), (c) dense near-surface sand layer (Dr ≈ 0.77), and (d) dense to very dense sand with slight vertical variability (Dr ≈ 0.7–0.9)
