Burgers-type empirical creep model for unsaturated soil considering matric suction
Shenzhen Daxue xuebao. Ligong banReservoir bank slopes are often in an unsaturated state due to water level fluctuations and atmospheric precipitation, which can easily trigger landslides. Therefore, it is necessary to develop a creep model for unsaturated soils that accounts for matric

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

The development of techniques for assessing compactibility of field soils. [PDF]
, 1995 During the last five decades, effects of soil compaction on crop growth and yield have been of increasing concern due to the introduction of heavier agricultural machinery.

The influence of suction changes on the stiffness of railway formation
, 2011 Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Advances in Thermo-Hydro-Mechanical Characterization and Modelling of Unsaturated Soils
In the last few decades, significant progress has been made towards characterizing and modelling the thermo-hydro-mechanical behaviour of unsaturated soils, including the decisive refinements of experimental techniques and the recent developments of ...

Modelling the Thermo-plasticity of Unsaturated Soils
, 2013 This paper presents a highly-coupled thermo-plasticity model for unsaturated soils. The effect of temperature on the mechanics of unsaturated soils is briefly addressed. Then the equations of the developed model, so-called ACMEG-TS, are detailed. Finally, the model is validated by the means of comparisons with experiments.

Pest Management Science, EarlyView.SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

The unsaturated shear strengths of two compacted collapsible soils
, 2011 A study was conducted into the engineering properties of two compacted collapsing soils, one from Port Augusta, South Australia, and the other from Khon Kaen, Thailand. Double oedometer testing was employed to determine the collapse indices of the soils.

Advanced hydro-mechanical coupling for unified constitutive modelling of unsaturated soils
A new unified constitutive hydro-mechanical model named ACMEG-s is formulated to improve modelling of unsaturated soils in free or constrained conditions. Indeed, due to particular mechanical and hydraulic boundary conditions, some natural and engineered
