Abstract: The paper describes a mechanism-based design approach for assessing spudcan penetration in soft nonuniform clay with an interbedded stiff layer. The proposed approach is developed on the basis of the results from a parametric ...

Abstract: Spudcan foundations for offshore mobile drilling rigs are large saucer-shaped foundations that can penetrate several tens of meters into soft sediments. The penetration depth is typically predicted by considering a ...

Abstract: In practice, natural soils exhibit strain-rate dependency and also soften as they are sheared and remolded. Traditional design approaches, however, have been developed based on idealized rate-independent perfectly plastic ...

Abstract: This paper explores the interpretation of undrained shear strength and layer boundaries from T-bar penetration resistance profiles in layered soft–stiff and stiff–soft clay sediments. The proposed interpretation framework ...

Abstract: This paper for the first time, to the best of our knowledge, reports 10 case histories of jack-up rig installation in different locations of the Gulf of Mexico consisting of seabed soil stratigraphy with weak surface (soft) ...

Abstract: A full-flow ball penetrometer is now routinely used in centrifuge testing for characterizing single-layer clay, silt, sand, and stratified soil samples. The behavior of the standard ball penetrometer (including the shaft) ...

Abstract: This paper describes a new approach for interpreting cone penetrometer data in soft-stiff-soft clay deposits. The identification of layer boundaries and interpretation of shear strength profile were of particular interest. ...
