...Sang Yeob Kim; Junghee Park; Hyunwook Choo; Jineun Choi; Jongmuk Won Permittivity can be one of the non-destructive methods to monitor many properties of soils. The objective of this study was to provide a comprehensive understanding of the permittivity of clay minerals through the measurement...

This paper investigates the entire evolution of the soil plug and its effects on the plug resistance of jacked open-ended piles in clay both numerically and analytically. Numerical analyses are undertaken with a large-deformation finite-element method to reveal...

... method (CE-EM) for ground improvement and reports a field test in soft clay. In this method, pre-installed capsules wrapped in carbon fibre cloth serve as the anodes, and metal tubes as the cathodes. The soil between the electrodes is reinforced through capsule-expansion-induced compaction and electro...

...Yanhao Zheng; Béatrice Anne Baudet; Matthew Richard Coop; Jean-Michel Pereira; Pierre Delage Carefully designed oedometer and triaxial tests were carried out on reconstituted illite–smectite rich Lucera clay to reach specific states of the critical state soil mechanics ( CSSM ) framework, which...

...Yohei Nakamichi; Catherine O’Sullivan; Paul Tangney; Stefano Angioletti-Uberti; Sara Bandera The response of clay to mechanical compression is highly dependent on its stress history. Generally, normally consolidated clays exhibit a relatively soft response, while overconsolidated clays exhibit...

...Mengwei Liu; J. Carlos Santamarina Clay self-assembly, fabric formation and fabric changes are governed by mineral composition, pore fluid pH and ionic strength. This study combines theoretical analyses, extensive data compilation and targeted experiments to investigate underlying processes...

Tests were carried out in a geotechnical centrifuge to explore how factors such as overconsolidation, cyclic amplitude and time affect the cyclic response of kaolin clay. The data indicate that the cone sleeve mobilises the remoulded...

This study begins by introducing the main implications and selected existing models for the time-dependent behaviours of soft soil...
