Abstract Insufficient resilience of the natural environment is one many problems with foundation linear structures, and ways to solve a structure stabilization soils. Fine-grained soils are problematic for traffic construction. The properties clay change due climatic conditions. They swell become plastic in presence water, shrink dry conditions, increase volume, freeze frost. Improving fine-gra...

Abstract Practical assessment of subgrade settlement induced by train operation requires developing suitable models capable describing permanent deformation characteristics filling under repeated dynamic loading. In this paper, load triaxial tests were performed on coarse-grained soil (CGS), and the axial strain CGS different confining pressures stress amplitudes was analysed. Permanent behavio...

A soil’s physical properties, mineral types, and pore structure significantly influence the shape properties of soil-water characteristic curve (SWCC). This study investigated effects types on SWCC pore-size distribution (PSD). Eight different soils from an alluvial deposit in Istanbul Adapazar?/Türkiye were used study. The test samples prepared by compaction at optimum water content (OWC) wet ...

BACKGROUND The divergent glacial histories of southern and northern Europe affect present-day species diversity at coarse-grained scales in these two regions, but do these effects also penetrate to the more fine-grained scales of local communities? METHODOLOGY/PRINCIPAL FINDINGS We carried out a cross-scale analysis to address this question for vascular plants in two mountain regions, the Alp...

Foundation is the lowest part of structure that bear all loads building above it. To create a solid building, foundation must be designed and worked thorough carefully. Standard penetration test one methods used to determine parameters soil where will built. In designing foundation, it often found reach hard with N-SPT = 50 even though at 30 also soil. This study aims analyze axial bearing capa...

Tidal marshes are important sites of silicon (Si) transformation, where dissolved Si (DSi) taken up by macrophytic vegetation and algal species is converted to biogenic silica (BSi), which can accumulate in the soil, be recycled within marsh, or exported adjacent coastal waters. The role restored created tidal these processes not well understood, nor impact nutrient enrichment at either plant e...

fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. in this process, a sheet is subjected to repetitive shear deformation conditions by utilizing asymmetrically grooved and flat dies through alternate pressing. in this study, a 2mm thick co...
