FE-Simulation of Subsequently Piled Foundations

摘要

Existing foundations of buildings can be piled subsequently to improve their bearing behaviour. The effort of subsequent piling depends on the initial state of soil as well as the load history. Model tests were carried out to study the influencing quantities, especially the loading history due to piling. The models tests were numerically simulated based on the FEM and on hypoplastic constitutive models for the soil.
