Numerical Modelling of Displacement Pile Resistance in Sand Ground. Part 2: Discrete Model, at Rest Stage, Load Test

The article presents a continuation of research results on numerical modelling displacement pile prototype ground (sand) resistance. Numerical resistance consists three stages: restitution initial soil stress state, the restoration state developed during installation and against applied load (pile test). Restitution induced in artificially created sand deposit after compaction procedures was realized by creating history defining experimentally determined over consolidation stresses. Installation effects were restored using well-known empirical approach based relation between CPT test data radial increase. Hardening model its parameters employed for substantiated first paper (Part 1) research. discrete pile, layers, pile-soil contact created. Modelling loading-unloading an incremental loading procedure. analysis validated with testing results.
