Corrected cone resistance
WebThe corrected cone resistance, qt, generally varies somewhat more than u2. Some of the cone types give good repeatability for sleeve friction, fs, while some show relatively large … Webshown in Figure 1. Although the chart is shown in terms of the corrected cone resistance qt, it can be used equally well with uncorrected cone resistance, qc, since the difference between qc and qt is small, except in soft fine grained soils that produce high penetration pore pressures.

Webwhere qt = the cone tip resistance corrected for unequal end area effects, ar = area ratio for the cone tip, and u2 = pore pressure measured behind the cone tip. The magnitude of this correction is typically quite small for sands (as u2 ≈ u0), but can be significant for soft clays (as u2 > u0), especially offshore due to WebThe CPT measures the cone resistance (q c) and the sleeve friction (f s) from which the friction ratio FR can be determined. FR is the ratio between the local sleeve friction and …
