Investigations regarding the re-use of sheet-piles.
Especially in recent years the topic sustainability and careful handling of environment are discussed more and more in politics and society. In geotechnical engineering there is great potential to deal more sustainable with the used resources. In this contribution, the possibilities of re-using steel sheet-piles are discussed. A main scope is set on the possibilities of recycling of the steel. Furthermore, the pull-out process of sheet-piles is discussed and problems during the pull-out process are described. In-situ often an increase of pull-out forces over time can be noticed. Several numerical investigations using finite element method are presented to investigate the possible factors which influence the increase in pull-out forces.
