Clay with free gas bubbles can be frequently encountered in the seabed. Gassy clay is an unsaturated soil, but its mechanical behavior cannot described using conventional soil mechanics because it has a composite internal structure saturated matrix and bubbles. The have either detrimental or beneficial effect on undrained shear strength of clay. New lower upper bounds for gassy are derived by c...

In this study, closed-form solutions are presented for two classical problems: the load exerted on strip or circular trapdoors and stability of tunnel headings in purely cohesive soils, considering both case a constant undrained shear strength linear vertical profile. The based minor modification Gunn's lower-bound plasticity solution. According to comparative numerical stress analyses finite-e...

Xanthan gum (XG) biopolymer-based soil treatment is an effective improvement method. In this study, we explored the effect of XG on undrained shear strength clays (kaolinite and montmorillonite) in chemically distinct pore fluids. Among fluids tested, kaolinite was highest kerosene, followed by deionized (DI) water brine. This study hypothesized that interparticle forces interactions dominated ...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

This study adopts Multivariate Adaptive Regression Spline (MARS) and Least Square Support Vector Machine (LSSVM) for prediction of undrained shear strength (su ) of clay, based Cone Penetration Test (CPT) data. Corrected cone resistance (qt ), vertical total stress (σv ), hydrostatic pore pressure (u0 ), pore water pressure at the cone tip (u1 ), and pore water pressure just above the cone base...

The present research study has been undertaken to carry out slope stability evaluation of the Jhika Gali landslide in Pakistan using GeoStudio. For this purpose, site geometry existing adjacent slided one was measured and samples were collected from site. in-situ moisture content 14% dry unit weight 18.63 kN/m3. Unconfined compression tests unconsolidated-undrained (UU) triaxial performed on re...
