The design and construction of shallow foundations for a multi-span viaduct for the East Taupo Arterial Project

April 17, 2012

Technical paper submitted for ANZ2012 geomechanics conference in Melbourne.

Abstract:

The new East Taupo Arterial includes a fourteen span viaduct with an overall length of 445m. The innovative structure was founded on shallow pads in alluvium and ignimbrite soils. The foundation design allowed significant construction benefits and efficiencies in a complex site that had difficult access. The design took advantage of the high strength soils. This paper summarises the geotechnical conditions at the bridge site as well as the challenges overcome during the design of the bridge. These included dealing with the response of the bridge to seismic events and the potential for displacement. The construction of the bridge is also described
