Organic soils are considered one of the most problematic soils due to their high
compressibility and low shear strength at small strains. Characterizing organic soils based …

The T-bar penetrometer is extensively used in offshore field investigation and laboratory
testing to evaluate the undrained shear strength of soft clay because of its reliability and …

This paper reviews the techniques used and some recent developments on in situ testing of
peat for the purposes of the design and surveillance of engineering structures. Geophysical …

Geotechnical engineering has matured sufficiently to contribute to resolving some of
society's grand challenges. The 56th Rankine Lecture considered one of the most pressing …

Proper understanding of the ball penetration behavior under centrifuge condition is
important for accurate soil property determination. In this study, large deformation finite …

The mechanical behaviour of deep-sea clay is crucial for oil and gas pipeline safety and is
traditionally assessed through in situ penetration testing, which is usually conducted in a low …

The findings from a comprehensive characterization of an organic soil deposit using multi-
faceted geotechnical field and laboratory investigations are presented. The field-testing …

A significant challenge for engineers working with peat is the estimation of the undrained
shear strength (su). This is particularly the case for shallow, slightly overconsolidated peats …

The T-bar penetrometer is currently used to characterise seabed sediments, mostly based
on the full-flow mechanism around the probe in soft clays. However, open and trapped …

This paper presents an experimental investigation on the ultra-soft marine soil recovered
from the seabed in deep-water areas in South China Sea (SCS). An improved T-bar …
