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

, 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 ...

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

Rainfall-induced differential settlements of foundations on heterogeneous unsaturated soils [PDF]

, 2013
This study stochastically investigates the rainfall-induced differential settlement of a centrally loaded, rigid strip foundation on an unsaturated soil with spatially varying values of either preconsolidation stress or porosity.

Cyclic behaviour of an unsaturated silty soil subjected to hydro-mechanical damage [PDF]

E3S Web of Conferences, 2020
The dynamic behaviour of unsaturated soil subjected to cyclic loading is considered using two stress state variables, net normal stress and matric suction. Though the influence of excess pore-water pressures in fully saturated soils has been investigated

Effect of compaction pressure on consolidation behaviour of unsaturated silty soil [PDF]

, 2004
The effect of compaction pressure on subsequent soil behaviour during isotropic consolidation has been investigated by conducting controlled-suction triaxial tests on samples of an unsaturated compacted silty soil.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Numerical analysis of evolution of the unsaturated soil micro-structure with capillary action during compression

Shuiwen dizhi gongcheng dizhi, 2022
Using numerical method to investigate the evolution of micro-structure in unsaturated soil is helpful to explain their physical mechanical. However, the evolution of micro-structure in unsaturated soil is not clear.

Numerical model for the determination of the soil retention curve from global characteristics obtained via a centrifuge [PDF]

, 2012
A novel centrifuge set-up for the study of unsaturated flow characteri\-stics in porous media is examined. In this set-up, simple boundary conditions can be used, but a free moving boundary between unsaturated-saturated flow arises.
