These costs are mainly due to dredging for maintenance of navigable water depth and subsequent relocation, transport, treatment and/or disposal of the dredged material. Of special concern is the treatment of sediments dredged from harbors. A pilot study to use dredged harbor mud as backfill material was conducted in the East Harbor of Bremerhaven, Germany between 2005 and 2007. During this project, a total of about 180,000 m3 of harbor mud was relocated by pumping behind a newly installed sheet piling, creating 14 acres of new harbor area. The subsequent occurrence of strong surface deformation of the backfill, indicating a partial collapse of the mud layer, highlights the need to better understand the geotechnical properties of harbor mud. The purpose of this work is to gain a better understanding of the usability of harbor mud as backfill material and therefore help improve the planning reliability in using dredged harbor sediments in future land reclamation projects.enBitte wählen Sie eine Lizenz aus: (Unsere Empfehlung: CC-BY)harbor mudbeneficial reuseshear strengthconsolidationvane shear testingoedometer500 Naturwissenschaften und Mathematik::550 Geowissenschaften, GeologieDissertationurn:nbn:de:gbv:46-diss000112327
