Elastic-viscoplastic constitutive model for overconsolidated unsaturated soils considering time effects and its verification

open access: yesYantu gongcheng xuebao, 2023
The time effects have a significant influence on the deformation characteristics of the overconsolidated unsaturated soils. Establishing an elastic-viscoplastic constitutive model for the overconsolidated unsaturated soils considering the time effects is

A numerical technique for modeling the behavior of single piles in unsaturated soils [PDF]

open access: yesMATEC Web of Conferences, 2021
Pile foundations are widely used in both saturated and unsaturated soils. In certain scenarios, these foundations are subjected to combined vertical and lateral loads.

Estimating Unsaturated Hydraulic Conductivity in Unsaturated Soil Using Soil Moisture Sensors

open access: yesInternational Journal of Integrated Engineering, 2023
Unsaturated hydraulic conductivity (K) is a measurement of soil water-retaining ability in unsaturated soil. The unsaturated hydraulic properties are necessary to predict the movement of water in unsaturated soil. The current study aims to create an alternative experimental device to estimate theKusing soil moisturesensors. The experimental

Revisiting the thermodynamics of hardening plasticity for unsaturated soils [PDF]

open access: yes, 2010
A thermodynamically consistent extension of the constitutive equations of saturated soils to unsaturated conditions is often worked out through the use a unique 'effective' interstitial pressure, accounting equivalently for the pressures of the ...

Modelling large deformation problems in unsaturated soils [PDF]

open access: yes, 2016
Applications of unsaturated soil mechanics often involve large deformations and displacements. This is the case of collapse behaviour of low density soils or the unrestrained swelling of expansive clays.

State-of-the-Art Review of Utilization of Microbial-Induced Calcite Precipitation for Improving Moisture-Dependent Properties of Unsaturated Soils

open access: yesApplied Sciences, 2023
Unsaturated soil is a form of natural soil whose pores are filled by air and water. Different from saturated soil, the microstructure of unsaturated soil consists of three phases, namely, the solid phase (soil particle), vapor phase, and liquid phase ...

Determination of Soil-Water Characteristic Curves of Unsaturated Sandy Soils Using Membrane Filter with Stainless Wire Mesh [PDF]

open access: yes, 2009
Soil-water characteristic curve (SWCC) is an important soil function in an unsaturated soil mechanics field for design and analyses of any unsaturated earth structures. Determination of SWCC is not easy and more so time consuming. Generally, ceramic disc

Numerical simulation of hydro-mechanical behaviors of unsaturated soils under fully undrained conditions

open access: yesYantu gongcheng xuebao, 2017
Volume changes take place during the fully undrained compression tests on unsaturated soils. It is more difficult to simulate the undrained mechanical behaviors of unsaturated soils than those of saturated soils.

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

open access: yes, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

Implicit integration algorithm of hydro-mechanical constitutive model for overconsolidated unsaturated soils and its application

open access: yesYantu gongcheng xuebao, 2018
The overconsolidated unsaturated soils emerge in many engineering projects. The constitutive models for unsaturated soils are very complicated due to the complex mechanical beahviour of overconsolidated unsaturated soils. A modified constitutive model is
