Abstract
The development of ship sizes is accompanied by special requirements for quay walls of harbour facilities. Within the scope of this research project, investigations will be carried out to improve the economic efficiency and safety of the design of combined sheet pile walls considering the installation phase as well as the final state.
In the design of the installation phase, the dynamic loading of the profiles during is only considered by empirical verification. Therefore, investigations should provide holistic design criteria for the optimized profile dimensioning in order to ensure not only economic efficiency, but also the profiles’ installation without damage and within tolerances.
When considering the embedment provided by weak soil layers as well as the partial welding of twin king piles, potential that could be activated for the load-bearing capacity remains unused. Based on the forerun project P 813, the profitability in terms of a wider range of installation situations shall be improved. In addition, the compatibility of the design with the latest changes of EN 1993-1-1 on bending buckling will be ensured. The design of the installation phase shall be improved by more economic regulations in EN 1993-5. An analysis of the cross-section classification of the intermediate piles shall ensure the consistency of the concept for partial plastic moment resistances existing in EN 1993-5 Annex C with the one to be included in EN 1993-1-1.
With EN 1993-5, the EAU 2012 and the forerun project, approaches for the design of combined pile walls, which have been optimized with regard to their economic efficiency and application safety, already exist. Despite the improvements made, potential still remains unused. The same applies to the simplicity and thus applicability of the design rules. This project shall exploit the unused potential, thus providing SMEs with significant benefits in terms of efficiency and safety when designing and installing combined pile walls.
