Modelling the degradation of penetration resistance during cyclic T-bar tests in a Gulf of Mexico clay

Installation and repetitive movement during the operation of a pipeline causes remolding and softening of the surrounding soil. Similar effects can occur around foundations during their operating life. The degradation of the undrained shear strength of soft clays near the seabed is a critical component of the design of subsea facilities, including pipelines and shallow foundations. This paper presents a two-stage strength degradation model based...
