Figure 6.
The graph depicts Cone Penetration Test, C P T, data interpretation based on Robertson’s two thousand ten methodology. It features a logarithmic scale for both axes, with the horizontal axis labelled, normalised friction ratio R f, ranging from zero point one to ten, and the vertical axis labelled, normalised cone resistance Q n, spanning from one to one thousand. Two data sets are illustrated with distinct markers, a green triangle represents C P T zero two at depths from twelve point seven to thirteen point two metres, while a red circle denotes C P T zero two from twelve point two to twelve point seven metres. Several curved lines demarcate soil categories including dense sand to gravelly sand, clean sands to silty sands, and various silt mixtures. The graph effectively communicates the relationship between cone resistance and friction ratio across different soil types, reflecting soil classification at specified depths.Interpretation of CTP02 results following the Robertson (2009) method
