Wesel Bridge, Germany

Wesel artist rendition The existing Rhine road bridge in Wesel was built in 1952 using the original pier foundations of the earlier 1916 bridge. This bridge is now being replaced by a new and exciting bridge design to carry the Bundesstrasse B58 into the town of Wesel, Westphalia, Germany.The new bridge under construction at Wesel will consist of a cable stayed semi-fan arrangement with an asymmetric inverted Y pylon.

As with many preliminary load testing projects, the aim of the testing programme was to confirm the design which was based on site investigation and soil parameters. Several piles were tested, each pile required one O-cell® to be installed within the pile shaft, size of cell and location within the shaft dependant upon the load required and the expected soil strengths.The final design could be optimised as a result of the tests performed. The use of an A9 strain extensometer string from Geokon above the O-cell® level, model 4911 sister bar strain gauges below the O-cell® level and direct measurement of toe movement with telltales allowed load distribution along the pile shaft to be determined and side shear resistance to be assessed.
