Design of foundations to Second Gateway Bridge: Brisbane

The Second Gateway Bridge duplicates one of Australia's largest bridges. Designed to mirror the existing bridge appearance, it is nevertheless quite different in underlying detail. With respect to the foundations, this is particularly evident in the adopted method of bridge articulation. The approach spans require the foundations to be relatively flexible in the longitudinal bridge direction to prevent large stresses developing in the spans due to concrete creep and shrinkage, but still resist large axial and transverse loads. This paper commences with a brief description of the geology of the bridge site including the regional faulting in the underlying rocks, which influenced the design of several of the pier foundations. The paper then provides an overview of the foundation systems adopted for the bridge, and describes some of the more interesting design features of the adopted foundation system.
