Abstract:
This paper presents the results of a laboratory study on the lateral stress in a vibrated sand. No. 3 Ottawa sand was tested on a snaking table providing vertical vibration, and at-rest lateral stress was measured using a modified oedometer ring. The test results show that the lateral stress in normally consolidated sand increases with vibration time. The magnitude of the increase in lateral stress is related to the density of sand and the intensity of vibration. For overconsolidated sand with a high coefficient of earth pressure at rest, the lateral stress decreases with vibration time. Stres

Abstract:
The mechanical behavior of a compacted unsaturated clay soil was experimentally investigated. Volume changes were investigated using a conventional odometer cell under a series of constant confining pressures, following a wetting path. The special loading paths were utilized to reflect field conditions associated with the compacted earth structure in earth filled embankment. The soils used in the experiments were taken from an earth dam. The compacted specimens were consolidated under k0-oedometer conditions. The volume change and the water content variation were measured during the tests. The

Abstract:
An experimental study regarding the hydro-mechanical behaviour of a Malaysian Kaolin is presented. Strain rate-controlled oedometer tests have been conducted on compacted samples. The influence of initial water content on the pore-size distribution (PSD) of compacted samples was investigated by Mercury Intrusion Porosimetry (MIP) tests. The drying path of the soil-water characteristic curve was experimentally determined for initially compacted samples and slurry samples. The preconsolidation stress was found to increase with increase in initial dry density and with decrease in initial water co

Abstract:
This study centred on the performance of the screw plate test (SPLT) to determine the deformability and consolidation characteristics of soft Bangkok clay. For comparison, a series of stress-path-controlled triaxial consolidation tests (tri) were carried out on good quality samples of Bangkok clay taken from the same testing sites and imposed with the same loading conditions as the screw plate tests. Undrained and drained moduli and coefficients of consolidation were obtained from the stress-path-controlled triaxial consolidation tests and were compared with the corresponding values of the scr

Full text
Abstract:
The mechanical behaviour of soils subjected to any stress path in which deviatoric stresses are present is heavily characterised by non-linearity, irreversibility and is strongly dependent on the initial state of stress. The latter, for the majority of geotechnical applications, is normally determined by the at-rest earth pressure coefficient K0, even though this state is valid, strictly speaking, for axisymmetric conditions and for zero-lateral deformations only. Many expressions are available in the literature for the determination of this coefficient for cohesive and granular materials both

Abstract:
This paper explores the effects of mechanical and hydraulic paths on the compressibility and water retention behaviour of compacted loess from Xi’an, China. Suction-controlled oedometer tests are combined with Mercury Intrusion Porosimetry (MIP) tests to evaluate the volumetric behaviour and the evolution of soil fabric for the compacted material. Suction-controlled tests results are analysed in the degree of saturation vs suction plane, using the water retention curve for as-compacted material as reference. Negligible volume change, and hence no movement of the as-compacted WRC, is observed u

Abstract:
This paper presents a simple thermo-elasto-plastic (TEP) constitutive model for saturated fine-grained soils, addressing thermal volume change, excess pore pressure and shear strength. The model incorporates a novel temperature-dependent plastic modulus formulation that attributes the thermoplastic strain to an internal state variable representing the thermal stabilization of soils due to cyclic thermal loading. It can capture the accumulative volume expansion of highly overconsolidated (OC) soils, and the accumulative contraction of normally consolidated (NC) and slight OC soils after several

Abstract:
The risk of geohazards associated with frozen subgrades is well recognized, but a comprehensive framework to evaluate frost susceptibility from microstructural characteristics to macroscopic thermo-hydro-mechanical (THM) behaviors has not been established. This study aims to propose a simple framework for quantitatively assessing frost susceptibility and compressibility in frozen soils. A systematic THM model was devised to predict heat transfer, soil freezing characteristics, and stress states in frozen soils. Constant freezing experiments and oedometer compression tests were performed on ben

Abstract Characterisation of freezing conditions (i.e. temperature and unfrozen water content) and stress states (e.g. stress level and specific volume) is critical to evaluate the thermo-hydro-mechanical properties of frozen soils. This study aims to utilise frozen soils’ electrical responses to characterise mechanical properties and interpret the associated frost heave phenomenon and compression characteristics. Frozen soils were prepared by freezing sand and bentonite at various temperatures (i.e. −5, −10, −20 °C), in which the electrical conductivity and frost heave were monitored. A modif

An experimental study of the K0of a loose reconstituted sand is presented. The experimental technique consists of drained vertical compression of a triaxial specimen using the strain path control, in which a positive control of the strain increments rather than the conventional stress increments is exercised. The method does not require the use of any lateral strain sensors as used in previous studies and is free from any side friction affects, typical of oedometer testing.

We studied one dimensional compressive behaviour of gap-graded granular mixtures, using the numerical simulations of the three-dimensional Discrete Element Method (DEM). Spherical particles of different size ranges were generated inside a cubical box to numerically create granular samples with the particle size distributions of a sand-like material mixed with different proportions of a uniform silt-size material. The DEM samples were subjected to one-dimensional compression similar to the loading path of the oedometer test in soil mechanics. Micromechanical characteristics behind the compressi
