Deep Soil Mixing in New Zealand – An update
Abstract
This paper presents recent developments in the use of deep soil mixing technique in New Zealand road slip repair works. A brief overview of New Zealand road maintenance history is presented, and the current role that deep soil mixing is playing is described. Valuable experience has been gained through the design and construction of deep soil mixing road remedial works. Key issues include composite behaviour and group effects of deep soil mixing of columns, and identifying failure mechanisms. The benefits of deep soil mixing are illustrated through case studies.
