ABSTRACT
The undrained shear strength increases more or less linearly with depth, with su (kPa) ranging between 1.08 z and 1.52 z (where z is the depth in meter), and the average strength gradient is close to the specified value of 1.3 kPa/m which is typical of deepwater conditions. The scatter in clay strength within the different centrifuge samples highlights the difficulty to obtain consistent and repeatable shear strength profiles with natural clay, clearly more difficult than with Speswhite kaolin.
