    Three-Dimensional Numerical Analysis of Pile Foundations Subjected to Coseismic Kinematic Demands and Transient Axial Load Redistribution

    A pile through a liquefying sand layer, shaken by the Chi-Chi record in a 3D model. The largest bending moments sit at the top and bottom of the liquefied layer.

    Comparative Numerical Study of Constitutive Models for Pile Foundations in Liquefiable Soils under Seismic Loading

    Three soil models, one pile, one earthquake. The choice of model alone can move the predicted depth of liquefaction by metres.

    Influence of Soft Clay Depth and Thickness on the Combined Axial and Lateral Response of Bored Piles: A Numerical and Field Investigations

    Full-scale load tests and a 3D model show how a buried layer of soft clay changes the way a pile settles and bends.

    Pile Performance in Liquefaction: A Comparative Analysis of Constitutive Models

    A review of the soil models used to simulate piles in liquefying ground, weighed for accuracy against computing cost.

    Behavior of Laterally Loaded Piles Installed in Layered Soils with a Soft Clay Layer

    A pile pushed sideways in a full-scale test, then in a 3D model. When soft clay lies within five pile diameters of the surface, a thicker layer means far more sideways movement.
