Temburong Bridge, Brunei – Ground Engineering - Part 2: Geotechnical Design

The new 30 km Cadangan Projek Jambatan Temburong (Temburong Bridge Project) in Brunei will provide a highway link between the two separated parts of Brunei, by spanning Brunei Bay. The complex geological setting brings particular challenges to the design and construction of the foundations required for the various forms of bridge structures. The varying depths of geological stratigraphy along the alignment and different loading conditions call for multiple deep foundation types, as well as different construction methodologies, to be adopted. Part 2 of this paper on the Ground Engineering aspects of the project focuses on the choices of foundation for different sections of the crossing, the geotechnical design approach and verification strategy, and the relevant computer analyses undertaken.
