The influence of deep excavation on adjacent pile behaviour is an important issue to ensure its serviceability and stability. In this paper, the effect loaded single in saturated cohesionless soil was investigated by 3D finite element method. After verification model using centrifuge test results found literature, a parametric study conducted varying most factors such as depth, distance from he...

Loosely packed cohesionless soils may suffer partial or complete liquefaction during seismic loading, causing significant structural damage. The dynamic behavior of liquefiable is widely investigated through element testing under controlled cyclic loading in undrained conditions. In this work, a total 20 stress-controlled triaxial experiments were conducted on saturated specimens clean sand to ...

Recent studies have shown that unsaturated soils lead to greater lateral pile capacity. This study aims experimentally assess how suction stress affects the response of piles in cohesionless soil. Two centrifuge tests were performed at 50 g evaluate effect Lateral loads applied monotonically on a single free-head displacement-controlledmanner maximum head displacement 0.44 m. The first test was...

The load-transfer factor () in the concentric cylinder approach is often used analytical formulation axially loaded piles. a constant value (in given pile slenderness ratio and soil condition) devised under elastic ‘pre-failure’ perfect pile–soil bonding conditions (a non-slip model). Given most numerical methods have already considered slipping stage, limitations of models recently been discus...

Using discrete simulations, we investigate the behavior of a model granular material within an annular shear cell. Specifically, two-dimensional assemblies of disks are placed between two circular walls, the inner one rotating with prescribed angular velocity, while the outer one may expand or shrink and maintains a constant radial pressure. Focusing on steady state flows, we delineate in param...
