Numerical Simulations of Pile Foundations Considering Small and Large Deformations

Within this chapter, special topics regarding pile foundations investigated by means of numerical simulations supported by model and/or field tests for validation are presented and first results are discussed. The focus lies on the presentation of the boundary value problems together with first numerical simulation results considering numerical simulation techniques for large or small deformations regarding the boundary value problems. The topics mainly discussed in the paper are investigations of the influence of reaction piles on the results of static pile load tests, simulations of soil-plugging in open-ended piles, as well as simulations regarding the influence of pile driving on the behaviour of early-age concrete in neighbouring piles.
