This paper discusses the role of the degree of capillary saturation (S') in modelling the coupled hydro-mechanical behaviour of unsaturated soils and proposes a new constitutive model for unsaturated soils by using the degree of capillary saturation (S') and the effective inter-particle stress (σ'ij). An enhanced hydraulic model is introduced to describe the hydraulic hysteresis and hydro-mechanical interaction in terms of the degree of capillary saturation (S'). In the proposed constitutive model, the shear strength, yield stress and deformation behaviour of unsaturated soils are governed directly by the above two constitutive variables, namely σ'ij and S'. To be in line with the existing finite element frameworks for unsaturated soils, the proposed model is eventually generalised to constitutive functions consisting of only primary variables such as the net stress (σij), suction (s) and degree of saturation (S). The typical performance of the model for simulating the characteristic trends of unsaturated soil behaviour is discussed in several different scenarios. The model is then validated against a variety of experimental data in the literature, and the results show that a reasonable agreement can be obtained using this new constitutive model.]]> Wed 19 Oct 2022 14:50:32 AEDT ]]> Triaxial apparatus equipped with elastic waves and matric suction measurement techniques https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:42032 Wed 17 Aug 2022 11:52:20 AEST ]]> Calibration of a coupled model to predict the magnitude of suction generated by osmotic technique with PES membranes and temperature effect https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:30847 Wed 11 Apr 2018 16:35:21 AEST ]]> Collapse behaviour of unsaturated compacted soil with different initial densities https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:4916 Wed 11 Apr 2018 11:54:47 AEST ]]> On the use of dimensional analysis to predict swelling strain https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:9526 Wed 11 Apr 2018 10:35:15 AEST ]]> An experimental investigation of unsaturated clay: volume change and microstructural considerations https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:22576 Tue 11 Dec 2018 14:59:52 AEDT ]]> Numerical modelling of vapour-ice desublimation process in unsaturated freezing soils https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:43812 Tue 04 Oct 2022 09:40:36 AEDT ]]> Field study on swelling-shrinkage response of an expansive soil foundation under high-speed railway embankment loads https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35562 Tue 03 Sep 2019 11:37:46 AEST ]]> Approach for predicting the relative coefficient of permeability of unsaturated soils with different initial void ratios https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:20610 Thu 10 Sep 2015 10:20:24 AEST ]]> Contaminant transport through an unsaturated soil linear beneath a landfill https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:1071 Sat 24 Mar 2018 08:32:11 AEDT ]]> Shear strength criteria for unsaturated soils https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:12488 Sat 24 Mar 2018 08:17:12 AEDT ]]> Constitutive modelling of unsaturated soils: discussion of fundamental principles https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:18159 Sat 24 Mar 2018 08:04:38 AEDT ]]> Explicit stress integration with reduced drift for Barcelona Basic Model https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:17984 Sat 24 Mar 2018 07:56:20 AEDT ]]> Interpretation of unsaturated soil behaviour in the stress-saturation space II: constitutive relationships and validations https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:16873 Sat 24 Mar 2018 07:54:47 AEDT ]]> A comparative study of stress integration methods for the Barcelona basic model https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:16872 Sat 24 Mar 2018 07:54:46 AEDT ]]> Interpretation of unsaturated soil behaviour in the stress - saturation space, I: volume change and water retention behaviour https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:16842 Sat 24 Mar 2018 07:53:29 AEDT ]]> Elastoplastic prediction of hydro-mechanical behaviour of unsaturated soils under undrained conditions https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:5420 Sat 24 Mar 2018 07:48:15 AEDT ]]> Poro-mechanical coupling influences on potential for rainfall-induced shallow landslides in unsaturated soils https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:29642 Sat 24 Mar 2018 07:41:54 AEDT ]]> Numerical study of dynamic soil compaction at different degrees of saturation https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:26448 Sat 24 Mar 2018 07:27:11 AEDT ]]> An analytical model for evaporation from unsaturated soil https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:36791 Mon 06 Jul 2020 11:24:41 AEST ]]>
