An approach for modelling spatial variability in permeability of cement-admixed soil
(Peer reviewed; Journal article, 2021)This paper presents a framework for modelling the random variation in permeability in cement-admixed soil based on the binder content variation and thereby relating the coefficient of permeability to the unconfined compressive ... -
Effect of freeze–thaw cycles on strength and ductility and microstructure of cement-treated silt with polypropylene fiber
(Peer reviewed; Journal article, 2021)In this paper, the strength, ductility and microstructure behavior of cement-treated silt with polypropylene fiber was studied by a host of experimental studies. The influence of fiber content (the weight of dry soil was ... -
Formulation of non-coaxial plastic dissipation and stress–dilatancy relations for geomaterials
(Peer reviewed; Journal article, 2020)Stress–dilatancy theories play a central role in the modeling of the plastic dissipation of geomaterials. There exist several mathematical frameworks for describing the stress–dilatancy behavior of soils. One of the limiting ... -
Investigation of the change in soil fabric during cone penetration in silt using 2D measurements
(Journal article; Peer reviewed, 2017)Interpretation of CPTU testing in silt is non-trivial because of the partially drained conditions that are likely to occur during penetration. A better understanding of the pore pressure generation/dissipation is needed ... -
Pore-water pressure development in a frozen saline clay under isotropic loading and undrained shearing
(Peer reviewed; Journal article, 2021)A systematical testing program on frozen Onsøy clay under isotropic loading and undrained shearing at different temperatures (− 3 ~ − 10 °C), strain rates (0.2~5%/h) and initial Terzaghi effective stress (20~400 kPa) was ... -
Transport coefficients and pressure conditions for growth of ice lens in frozen soil
(Peer reviewed; Journal article, 2021)In this paper, the transport of sub-cooled water across a partially frozen soil matrix (frozen fringe) caused by a temperature difference over the fringe, is described using non-equilibrium thermodynamics. A set of coupled ... -
Unified bounding surface model for monotonic and cyclic behaviour of clay and sand
(Journal article; Peer reviewed, 2022)This paper presents a constitutive model enabled to simulate monotonic and cyclic behaviour of clay and sand in a unified framework. The bounding surface concept has been utilized to predict a smooth transition from elastic ...
