THE FARO BRIDGES: STUDIES AND IMPLEMENTATION

A comprehensive account is given of the Danish South Motorway bridge which forms part of the road connection E4 between Scandinavia and the continent across the waters between Sjaelland and Falster. Details are given of the extensive pre-tender site investigations which included geotechnical and hydraulic investigations, ice measurements, ship recordings and archaeological field work. After sketch proposals and preliminary projects the resulting tender project specified a bridge consisting of continuous girders with 80 m spans with a cable stayed bridge across the deep channel between Falster and the island of Faro. Details are given of the design and construction of the bridge with particular reference to the design and execution of the concrete structures at sea including their foundations. In deep water pier foundations are on heavy steel raking piles driven in a pattern to utilise their bending and shear strength. In shallower water, piers are on footing foundations constructed within dewatered steel sheet pile cofferdams. (TRRL)
