A laboratory study of the expansion of an Irish pyritic mudstone/siltstone fill material
(Elsevier, 2012-11-07)
Extensive damage to dwellings in the east of Ireland, arising from the expansive pyritic fill material used beneath the floor slabs, prompted the laboratory study presented in this paper to quantify the expansion and study ...
Stone column settlement performance in structured anisotropic clays: the influence of creep
(Elsevier, 2016-07-15)
The recently developed elasto-viscoplastic Creep-SCLAY1S model has been used in conjunction with PLAXIS 2D to investigate the effectiveness of vibro-replacement in a creep-prone clay. The Creep-SCLAY1S model accounts for ...
Modelling stone column installation in an elasto-viscoplastic soil
(Taylor & Francis, 2014-12-31)
The majority of numerical studies investigating stone column performance have used “wished-in-place” columns (no installation effects) in conjunction with elastoplastic soil models (no viscous effects). In the first part ...
Empirical correlations for the compression index of Irish soft soils
(ICE Institution of Civil Engineers, 2014-09-08)
Numerous correlations have been developed in the literature relating the compression index Cc of soft soils to simple index properties that serve as a useful reality check on oedometer test results. However, many of these ...
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)
This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ...
Biaxial loading of offshore monopiles: numerical modelling
(American Society of Civil Engineers, 2016-05-18)
In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ...
Shaft resistance of driven cast-in-situ piles in sand
(NRC Research Press, 2015-06-25)
Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests ...
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)
In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ...
Numerical modelling of pile foundation angular distortion
(Elsevier, 2015-05-16)
In this paper, the PLAXIS 3-D Foundation finite element (FE) software package, in conjunction with the nonlinear Hardening Soil (HS) constitutive model, is employed in an extensive parametric study of the angular distortion ...
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)
The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ...
