Stone column settlement performance in structured anisotropic clays: the influence of creep
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 ...
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 ...
Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ...
Statistical grain size effects in fretting crack initiation
A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ...
Modelling of fretting in the pressure armour layer of flexible marine risers
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 ...
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 ...
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.
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 ...
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 ...
An analytical approach for the prediction of single pile and pile group behaviour in clay
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 ...
