Jacked Piling in Australia

Dr Peter W Mitchell

Jacked piling is increasingly being used in China, Japan and South-East Asia, and was introduced into Australia in 1998. Jacked piles have the advantages of being vibration free, creating minimal noise, being pollution free, having a high operational accuracy, not generating high transient driving stresses and providing a type of static load test as part of the installation process. However, there are many aspects of jacked piling that require special attention by geotechnical engineers over that of conventional piling methods. Many of these aspects are now incorporated into AS 2159-2009 “Piling-design and installation”. This presentation addresses several of these aspects, based on Dr Mitchell’s experiences over the thirteen year period since the introduction of large scale jacked piling into Australia.
