Modified instrumentation and results of stress and deformation monitoring at the new quay wall construction – Container Terminal Altenwerder, Port of Hamburg

摘要

In the last couple of years, the Institute of Soil Mechanics and Foundation Engineeringrnat the Technical University of Braunschweig (IGB·TUBS) has carried out extensive measurementsrnat five different quay wall constructions in the port of Hamburg. One important result, thatrnwas received at all different investigations is: the total load on the wall is nearly constant. The loadrnon the retaining wall is not dependent from the tidal water level. The extrema of water- and earthpressurernloads occur postponed. The loads on the water pressure are almost completely compensatedrnwith the change of the effective stresses. Following these results and experience, thernIGB·TUBS has carried out a more extensive measurement concept for the first construction phasernof the new Container-Terminal Altenwerder in the port of Hamburg. This report contains informationrnon the innovations of the quay construction and the modification of some measurement instrumentsrnand first results of the axial forces/skin friction of the raking pile.
