Abstract

The Port of Brisbane (PoB) is located at the mouth of the Brisbane River at Fisherman Islands, Queensland, Australia. In 1999, PoB decided to expand into the sea using reclamation. While the readers are advised to browse the SHRP2 website and FHWA manual, in this book, the authors have simplified the guidance offered to provide a soft clay specific investigation and design process to identify and select, and carry out preliminary designs for ground improvement. The initial alert to the presence of soft clays should be made during the desk study of available information. Groundwater chemistry may also be important for some type of ground improvement methods. Mitchell and Jardine provide a simple but illustrative example of foundation options for a building to be constructed over a site underlain by soft clay. Usually, numerical analysis is considered a minimum for major projects because of the ramifications associated with differential settlements at critical locations.
