The cavity expansion approach has been a popular tool to interpret wide range of geotechnical problems over the last several decades. Most previous research focused on cylindrical and/or spherical cavities, whereas nonstandard cavities have received much less attention. To address this shortcoming, paper presents general theoretical framework for two-dimensional (2D) displacement-controlled und...

This paper provides insight into the behavior of a stiffened caisson anchor under inclined cyclic loading in calcareous silt. A series tests was conducted beam centrifuge. monotonic test first performed, quantifying pure capacity, and then four varying mean load, amplitude, number cycles. Cyclic soil characterization T-bar were linked. Undrained led to generate excess pore pressure, resulting d...

Dynamic loadings such as earthquake loadings can generate considerable principal stress rotation (PSR) in the saturated soil. The PSR without changes of principal stress magnitudes can generate additional excess pore water pressures and plastic strains, thus accelerating liquefaction in undrained conditions. This paper simulates a centrifuge model test using the fully coupled finite element met...

Viscous rate effects are commonly observed in clay soils in applications that involve high strain rates such as free falling penetrometer tests. Viscous rate effects are not well studied thus affecting reliable interpretation of these applications. This paper presents an investigation of viscous rate effects in clay using laboratory rate studies covering a wide range of strain rates (6 orders o...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...
