Physical modelling of piles under lateral loading in unsaturated soils

Centrifuge modelling of long piles subjected to lateral loading with high load eccentricity in sand

In this research paper, five centrifuge lateral loading tests of long piles with a considerable load eccentricity were carried out in the sand to investigate the impacts of the load eccentricity and pile length changes on the lateral behavior of a flexible pile beside the determination of experimental p-y curves. Comparing experimental test results with the recommended API (American Petroleum ...

A constitutive model for unsaturated cemented soils under cyclic loading

On the basis of plastic bounding surface model, the damage theory for structured soils and unsaturated soil mechanics, an elastoplastic model for unsaturated loessic soils under cyclic loading has been elaborated. Firstly, the description of bond degradation in a damage framework is given, linking the damage of soil’s structure to the accumulated strain. The Barcelona Basic Model (BBM) was cons...

Numerical Analysis of Piles in Elasto-plastic Soils under Axial Loading

A finite element model has been developed to simulate nonlinear response of piles/drilled piers under axial loading. The nonlinear stress-strain behaviors of soils are modeled via Drucker-Prager and von Mises type plasticity. A parametric study is carried out to address the influence of various factors, such as soil friction approximation, dilatancy, effect of interface element and shear streng...
