An analytical approach for the prediction of single pile and pile group behaviour in clay
(Elsevier, 2016-02-21)In this paper, the 't-z method' is employed to describe the nonlinear behaviour of a single pile and is used to obtain simplified predictions of pile group behaviour by considering the interaction between two-piles in ... -
Appraising stone column settlement prediction methods using finite element analyses
(Springer Verlag, 2014-09-26)Numerous approaches exist for the prediction of the settlement improvement offered by the vibro-replacement technique in weak or marginal soil deposits. The majority of the settlement prediction methods are based on the ... -
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 ... -
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ... -
Creep improvement factors for vibro-replacement design
(ICE Publishing, 2017-02)Although the vibro-replacement stone column technique is being deployed increasingly in soft cohesive soil deposits in which creep settlements may be significant/dominant, the majority of existing stone column settlement ... -
Discussion: Interaction factor for large pile groups
(ICE Publishing, 2016-09-27)The authors present an interesting paper on the use of the interaction factor method (IFM) for settlement analysis of large pile groups. -
Dynamics and function of intracellular carbohydrate in activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)Recovery of biodegradable plastics from activated sludge is a promising sustainable technology. In this study, polyhydroxybutyrate (PHB) ¿ a biodegradable plastics material - was produced by activated sludge performing ... -
An embodied carbon and embodied energy appraisal of a section of Irish motorway constructed in peatlands
(Elsevier, 2015-01-29)In addition to the customary drivers of cost and timely project delivery, embodied energy (EE) and embodied carbon (EC) have come to prominence in recent years as major design considerations in all aspects of large-scale ... -
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 ... -
Engineering in Communities Learning by Doing
(2012)Purpose The purpose of this paper is to focus on a number of initiatives in civil engineering undergraduate programmes at the National University of Ireland, Galway (NUIG) that allow students to complete engineering ... -
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 ... -
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ... -
Ground heave induced by installing stone columns in clay soils
(ICE Publishing, 2013-12)Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ... -
An improved experimental test set-up to study the performance of granular columns
(ASTM International, 2006-03)This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine ... -
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 ... -
Microplastics in sewage sludge: effects of treatment
(American Chemical Society, 2016-12-12)Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ... -
Modelling of fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-03-04)This paper presents a computational methodology for frictional contact mechanics of the pressure armour layer in flexible risers. This will allow, for the first time, quantification of key fretting variables, such as contact ... -
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 ... -
Nitrogen-limitation-induced carbon and phosphorus fluxes in anaerobic/aerobic sequencing batch reactors
(Elseiver, 2010)Enhanced biological phosphorus removal (EBPR) has been applied widely in wastewater treatment plants. However, deterioration or failure of EBPR often happens because: (i) of the dominance of glycogen-accumulating organisms ... -
