BRUCE HIGHWAY - TINANA INTERCHANGE
CGC provided the detailed design of the 130m abutment reinforced soil structure retaining walls for the construction of a new overpass over the Bruce Highway.
The geotechnical design included sliding, bearing and overturning analysis of the retaining walls, global slip analysis and settlement analysis. Challenges included a variable backslope profile and the bridge abutment not perpendicular to the wall, requiring the development of detailed geotechnical models.
