Abstract Tailing dams and waste dumps formed by the accumulation of mine wastes are usually at long-term unsaturated state under evaporation consolidated drainage conditions. Soil-water retention relation is one key constitutive relations to analyze seepage processes in tailing dumps. In this study, typical coarse- fine-grained tailings from a metallurgical were chosen study soil-water characte...

The bentonite pellet-contained material (PCM) is a desired joint sealer for high-level radioactive waste repositories. During the operation of repository, however, PCM unsaturated most period. water retention capacity and permeability can thus directly affect buffer barrier seepage, nuclide migration, healing. Moreover, performance be strongly influenced by particle size pellets dry density. In...

This paper aimed to study the soil–water characteristics and stability evolution law of rainfall-induced landslide. Taking two landslide events in Siwan village as an example, formation conditions disaster were analyzed. Additionally, deformation destruction mechanisms landslides discussed in-depth. The hydraulic conductivity analyzed based on TRIM experiment results. Geo-Studio numerical softw...

Compacted loess soil is used as a geo-material in many engineering projects, such building foundations and highway embankments. Water infiltration characteristics post settlement of the compacted large construction projects Northwest China have received increasing attention from researchers investors. These behaviors are closely related to water characteristics. This study aims investigate char...

The deterioration of soil physical properties had led to a decrease in soil–water availability facility agriculture. Thus, an experiment was set up with five treatments 0% (CK, No additives), 3% biochar (BA3, Mass ratio), earthworm manure (QA3), 5% (BA5), and (QA5) investigate the effects on hydraulic characteristics under greenhouse conditions. including bulk density (BD) total porosity (TP) w...

Extreme rainfall is a common triggering factor of landslide disasters, for infiltration and pore water pressure propagation can reduce suction stress shear strength at the slip surface. The subsurface hydrological model an essential component in early-warning system rainfall-triggered landslides, whereas soil moisture simulated by Darcy–Richards equation could be significantly affected uncertai...

Differential protection normally detects short circuits and ground faults in the windings of a power transformer its terminals. Inter-turn refer to flashovers among electrodes that arise only similar type physical winding. can be examined when adequate sum turns is served as short-circuited. In electrical protection, it difficult detect inter-turn faults. An fault small magnitude based on limit...

Expansive soils are problematic and viewed as a potential hazard for buildings structures due to swell shrink phenomena. The damaging effect of these is strongly correlated with the soil-water characteristics expansive present in shallow depth. seasonal wetting-drying cycle vital fluctuating moisture content surficial soils. As such, remain unsaturated most time high absorption capacity. Theref...

This study aims to apply geophysical methods determine the Specific Yield (Sy) and Groundwater Level (GWL) in an unconfined aquifer of Pingtung Plain South Taiwan. Sy is important hydraulic parameter for assessing groundwater potential. Obtaining specific yield a large area impractical due limited coverage high cost pumping test, which limits potential evaluation regional groundwater. Therefore...
