Sammendrag
Interpretation of remoulded shear strength in soft clays based on lab and/or in-situ traditional testing can be simple and challenging, depending on the adopted approach. A new approach that uses CPTU data in the calculation of the slope parameter aq = Bq - 1/Q, together with laboratory fall cone and field vane shear tests data from 15 sites, demonstrates that when aq > 0.5, the clay under study can be considered as sensitive clay. The proposed relation is intended to be used as a first-order approximation of the remoulded shear strength that can be used as an indication of clay sensitivity. Further data and extended verification of the proposed approach are encouraged in the future for further validation A new approach for evaluation of remoulded shear strength in clays using the cone penetration test
