Figure 1.
The graph depicts cone resistance q c on the horizontal axis and penetration z on the vertical axis. Three curves represent Loose, Medium dense, and Dense soil conditions. The Loose curve lies closest to the axis, Medium dense is intermediate, and Dense extends farthest. Horizontal dashed lines divide the profile into the shallow zone, and Transition, and the deep zone at different depths. The curves show increasing cone resistance with penetration, with Dense soil maintaining the highest resistance throughout and Loose soil the lowest.Idealised shallow depth cone resistance profiles in uniform loose, medium dense, and dense sand
