Performance of battered mini driven pile group in basaltic clays: Field testing and numerical modelling

Abstract

A new battered mini driven pile group footing system developed recently in Victoria, Australia shows considerable advantages compared to traditional reinforced concrete footings. It can be manually handled and installed with light jackhammers without the need for an excavation or drilling. Soil disturbance is also much lower than other types of foundation systems and being concrete-free system leads to a shorter construction time and lower cost and carbon-footprint. This new system is known as Surefoot. One of the best methods to ascertain the performance of foundation systems is field load testing. To evaluate the ultimate capacity of this system, eight static compression and pull-out tests..
