The increase in the as-compacted degree of saturation in loose samples (dry density ≤1·3 Mg/m3) produces an enhancement in the proportion of macro pores, thus increasing keff, as a consequence of modifications in the pore size distribution. A threshold value has been identified, above which further increase in degree of saturation causes a reduction in the proportion of macro pores, and therefore in keff. A new proposal for estimating the air permeability is proposed in this paper based on the determination of a pore size parameter obtained from MIP data. The proposed approach seems capable of describing the evolution of air permeability for the whole spectrum of compaction states, including specimens subjected to wetting and drying paths.]]> Wed 10 Aug 2022 13:37:24 AEST ]]> Agent-based modelling for environmental impact of renovation waste in Shenzhen, China https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38542 Wed 07 Feb 2024 16:35:15 AEDT ]]> A microstructural perspective on soil collapse https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38362 Tue 22 Feb 2022 14:09:32 AEDT ]]> A new large step-tapered hollow pile and its bearing capacity https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38307 3D software. The vertical bearing capacity was assessed by considering the influences of the width and number of the variable cross-sections and the soil characteristics around the pile. In addition, new large STH piles of two different forms were assessed to expand the practical application of such piles. The results showed that, for a large-diameter pile, the concrete utilisation rate and the vertical bearing capacity of the pile were improved by the design of hollow and variable cross-sections. The optimal range of the taper angle for the large STH pile was found to be 2·68–5·36° and the optimal number of variable cross-sections was found to be between two and four. The bearing capacity increased with an increase in the soil shear strength parameters and the pile was deemed suitable for stiff strata. The results of this work could facilitate design practice for large STH piles.]]> Thu 26 Aug 2021 11:53:32 AEST ]]> Comparison of finite-element limit analysis and strength reduction techniques https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23409 Sat 24 Mar 2018 07:13:55 AEDT ]]> Reinforcement corrosion of the Phoenix caissons after 75 years of marine exposure https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46230 Mon 14 Nov 2022 12:32:58 AEDT ]]> Critical state behaviour of an unsaturated high-plasticity clay https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39050 Mon 02 May 2022 11:01:35 AEST ]]> A new technique for deep in situ measurements of soil water retention behaviour https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45443 Fri 28 Oct 2022 13:54:23 AEDT ]]> Effect of soil biology and pore water chemistry on a lakebed sediment https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41717 Fri 12 Aug 2022 09:01:24 AEST ]]>
