Title:	Einsatz von Fertigteilen im massiven Verkehrswasserbau
Abstract:	In den kommenden Jahren steht im Bereich der Wasserstraßen- und Schifffahrtsverwaltung des Bundes (WSV) eine Vielzahl an großen Baumaßnahmen in den Bereichen Ersatzneubau und Grundinstandsetzung von massiven Wasserbauwerken an. Diese Maßnahmen müssen trotz hoher Anforderungen an die Dauerhaftigkeit und Verfügbarkeit massiver Wasserbauwerke zuverlässig, effizient und kostengünstig abgewickelt werden. Der Einsatz von Fertigteilen und Teilfertigteilen aus Stahlbeton bietet in diesem Zusammenhang interessante technische und wirtschaftliche Möglichkeiten. Das diesbezügliche Anwendungspotenzial soll gezielt analysiert, bewertet und genutzt werden. Die notwendigen Voraussetzungen für eine systematische Verwendung von Fertigteilen im Wasserbau bis hin zu Regelungen für Bemessung, Baustoffe und Bauausführung werden im Rahmen eines FuE-Vorhabens der Bundesanstalt für Wasserbau (BAW) erarbeitet. Use of precast reinforced concrete elements in massive hydraulic engineering In the coming years, a large number of major construction measures is being expected in the Federal Waterways and Shipping Administration (WSV) for replacement and overhaul of massive hydraulic engineering structures. These measures must be carried out reliably, efficiently and cost-effectively despite high demands on the durability and availability of massive hydraulic structures during their service life. In this context, the use of precast and semi-precast (with in-situ concrete topping) reinforced concrete elements offers interesting technical and economic possibilities. The resulting application potential is to be specifically analysed, evaluated and used. The necessary requirements for a systematic use of precast reinforced concrete elements in hydraulic engineering including the corresponding regulations for design, building materials and construction are being developed within the framework of an R&D project of the Federal Waterways Engineering and Research Institute (BAW).
