Mobilisation of bacteria in a fine-grained residual soil by electrophoresis

Journal of Hazardous Materials, 2009
An investigation of electrokinetic bacterial mobilisation in a residual soil from gneiss is presented here. The experimental program aimed at assessing the efficacy of electrophoresis against the electro-osmotic flow to transport endospores of Bacillus subtilis LBBMA 155 and nitrogen-starved cells of Pseudomonas sp. LBBMA 81.

Quantifying Soil Particle Settlement Characteristics through Machine Vision Analysis Utilizing an RGB Camera

Agriculture, 2023
Soil particle size distribution is a crucial factor in determining soil properties and classifying soil types. Traditional methods, such as hydrometer tests, have limitations in terms of time required, labor, and operator dependency.

Field instrumentation for performance assessment of Geobarrier System

E3S Web of Conferences, 2016
The saturated hydraulic conductivity of a coarse-grained material is normally higher than that of a fine-grained material. However, the unsaturated hydraulic conductivity of the coarse-grained material decreases much faster than that of the fine-grained ...

Influence of Loosely Bound Water on Compressibility of Compacted Fine-Grained Soils

Advances in Civil Engineering, 2020
This study aimed to investigate the influence of loosely bound water (LBW) on the compressibility of compacted fine-grained soils and accurately determine the soil’s compression index. Four fine-grained soils (i.e., heavy clay, heavy silt, lean clay, and

Settlements in Fine-Grained Soils Under Cyclic Loading

Soils and Foundations, 2001
ABSTRACT Based on the methods previously presented by the authors (Yasuhara et al., 1992, 1994, 1996) for predicting the degradation in strength and stiffness of soft clays in the course of cyclic loading, a methodology has been developed to estimate the cyclic loading-induced settlements.

Feasibility study of a new unsaturated three-layer landfill cover system

E3S Web of Conferences, 2016
As an improvement of the two-layer cover with capillary barrier effect (CCBE) (i.e. fine-grained soil overlying a coarse-grained soil), a new three-layer landfill cover system is proposed and investigated for humid climate.

Bridging traditional and conventional knowledge for soil classification in landslide-prone areas using exploratory factor analysis

Frontiers in Environmental Science
IntroductionUnderstanding soil movement and landslide susceptibility requires accurate soil classification. Traditional knowledge (TK) from ancient Indian texts describes soil color, texture, smell, and taste as key indicators, yet such qualitative ...

Discrimination methods for dispersivity of fine-grained soils based on dispersive mechanisms

Yantu gongcheng xuebao, 2023
The crumb tests, the pinhole tests, the double-hydrometer tests, the pore water soluble cation tests and the exchangeable sodium ion percentage tests are the common methods for identifying the dispersivity of the fine-grained soils, which are complex and

Swelling Potential of Fine‐Grained Soil: Theory, Determination, and Validation

Water Resources Research
Swelling potential (SP) has long been used as a terminology to describe a soil's expansibility. It is commonly defined in terms of pressure or deformation under certain constraints.

Mesoscopic numerical tests on seepage failure characteristics of coarse grained soils

Yantu gongcheng xuebao, 2018
To deeply explore the influences of seepage failure on permeability feature of coarse grained soils, based on the analysis of indoor experiment results of seepage failure tests on coarse grained soil samples, the software named PFC3D is employed to ...
