An MASW survey for geotechnical engineering in an urban setting - an application to pre-tunnelling investigation.

Abstract

As a part of the Airport Tunnel project in Brisbane, an MASW survey was carried out to investigate the nature of the fill site of an old rock quarry. The main target of the survey is the depth of the landfill after the quarrying operation to avoid the tunnelling penetrate the fill material. The site is currently used as a shopping centre car park in an inner suburb of Brisbane along one of the main roads. To avoid excessive noise, the survey took place at night.
