The problem of a spherical cavity which is embedded in a linear, fluid-infiltrated, elastic porous medium and which is subjected to the sudden quasi-static application of a stress at the cavity boundary is solved. It is demonstrated that the deformation of the cavity is homogeneous regardless of the boundary condition imposed on the pore fluid at the cavity wall. For the case in which the pore ...

This study aims to investigate the impact of initial mean effective stress on thermo-mechanical behavior saturated normally consolidated kaolinite clay. Specifically, a series isotropic thermal triaxial tests in cell equipped with image analysis for volume change tracking was performed understand drained response as well undrained shear strength before and after heating. Anisotropically clay sp...

Abstract Traditionally, Biot’s formulation is employed to model the behavior of saturated soils. The $$u-p_w$$ u - p w (solid displacement–pore water pressure) can be considered as standard one, since involves a g...

To investigate the strength and deformation characteristics of gravelly sand on Qinghai-Tibet Plateau under different stress paths, a series triaxial shear tests was conducted confining pressures 50–400 kPa in four types path conditions conventional compression (CTC) (drained undrained), (TC), reduced (RTC). We can see from test results that samples show strain hardening contraction CTC (draine...
