Unsaturated soils in the context of tropical soils
Soils and Rocks, 2021 Abstract The practice of geotechnical engineering in tropical climate regions must consider the use of unsaturated soil concepts. However, these concepts must also take into account the specific behavior traits of tropical soils, particularly those related to soil aggregation, pore structure, and mineralogy.

UH model for ideal expansive unsaturated soils
Yantu gongcheng xuebao, 2023 The expansive unsaturated soils are characterised by the behaviour of volume increase and strength reduction during wetting, which may cause nonuniform foundation settlement and further result in cracking of overlaying buildings.

Strength Theory Model of Unsaturated Soils with Suction Stress Concept
Journal of Applied Mathematics, 2013 A theoretical model is developed for describing the strength property of unsaturated soils. The model is able to predict conveniently the strength changes of unsaturated soils undergoing repeated changes of water content. Suction stress is adopted in the

Effect of soil-water characteristic curve on shear strength of unsaturated sandy soils
Yantu gongcheng xuebao, 2020 The experimental measurements of the shear strength of unsaturated soils are uncommonly emloyed in the practical engineering because the unsaturated experimental measurements are time-consuming and costly. Instead, the shear strength of unsaturated soils

Dielectric permittivity method to monitor (liquid) water content in unsaturated soils, frozen soils, and snow [PDF]
E3S Web of ConferencesMonitoring (liquid) water content is key to inform early-warning systems for unsaturated, permafrost, and snow slopes. Dielectric permittivity-based sensors are widely used to monitor (liquid) water content in unsaturated soils and include the well-known

E3S Web of Conferences, 2016 Several researchers have reported that Bishop’s mean effective stress decreases in unsaturated soils under fully undrained cyclic loading conditions, and unsaturated soils are finally liquefied in a similar manner as saturated soils.

A structural bounding surface constitutive model for unsaturated soils and its verification
Yantu gongcheng xuebao, 2022 Most soils have both unsaturated and structural properties. The establishment of a constitutive model of unsaturated soils considering the structure is of great significance for analyzing the mechanical properties of unsaturated soils.

Extending modified Cam-Clay to unsaturated soils by incorporating a scaled stress variable
, 2023 This paper extends the modified Cam-Clay model to describe the behaviour of unsaturated soils by replacing the effective stress with the scaled stress. The scaled stress accounts for the mechanical effect of capillarity by factoring Bishop’s stress with ...

, 2010 The paper presents a comparison between compacted and reconstituted soils in terms of microstructure, and hydraulic and mechanical response. It is commonly assumed that reconstituted and compacted soils exhibit a fundamentally different behaviour due to different microstructures.
