The CPT tests were carried out in downhole mode. The tests were carried out in several strokes and having each stroke length of 3 m. The initial part of each stroke was removed due to soil disturbance [ 11 ].
Webb27 aug. 2024 · The relative density is an important state parameter in the determination of engineering properties of marine sands. Existing industry-acknowledged cone penetration test (CPT) correlations to relative density have been developed almost exclusively from the results of calibration chamber testing performed at stress levels higher than 50 kPa.
