Abstract This paper presents a series of studies in which traditional upper bound plastic limit analysis (PLA) methods are modified to accommodate non-linear strength profiles which correspond to soils with crust. The collapse mechanism presented comprises a surface failure wedge, a flow-around...

The use of piezocone data in this manner allows the development of a site-specific family of undrained shear strength profiles that are continuous throughout the depth of testing. This profile can complement data from the soil sampling program which inherently...

An instrumented pipe section is then lowered onto the test bed and measurements are made during embedment of the test pipe...

... Abstract Accurate measurement of the shear strength profile in the upper 1 m of soft sediments is crucial for pipeline and riser design, particularly for deep water developments. In this paper, some existing approaches for the strength characterization of seabed surficial sediments...
