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 ...
Stone column effectiveness in soils with creep: a numerical study
(Taylor & Francis, 2016-03-16)
While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ...
Analysis of jacking force data for microtunnels in glacial till at Kilcock, Ireland
(IOS Press, 2011)
Although the application of microtunnelling to pipeline construction has grown considerably in Ireland in recent times, there is very little published guidance on the jacking forces that might be expected in Irish ground ...
The use of digital resources in civil engineering education: student learning and achieving accreditation criteria
(Cambridge Scholars Publishing, 2012)
The use of digital resources in higher education has risen significantly over the last ten years and will continue to do so for the foreseeable future. The challenge for educational instructors is in determining how to ...
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 ...
Factors affecting Embodied Carbon/Embodied Energy associated with ground improvements techniques for construction on peat
(NUI Galway, 2012)
In addition to the traditional drivers of cost and timely programme delivery, embodied energy (EE) and embodied carbon (EC) have emerged as major considerations in all aspects (including geotechnical) of large construction ...
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 ...
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 ...
Heave-ho! A laboratory model of an underfloor environment incorporating pyritiferous fill
(NUI Galway, 2016)
Damage to domestic dwellings in the greater Dublin area of Ireland caused by the expansion of underfloor fill material containing pyrite has become a high-profile national problem in recent years. In this paper, a novel ...
