Geosurveys innovation
Dr Andi Pfaffhuber
The presentation will use a range of case studies to illustrate how geophysical methods are being used innovatively to deliver geotechnical efficiency. The presentation illustrates:
- How radar satellite data is used to track infrastructure- and slope settlement to millimetre resolutions. Illustrations include a hydro dam and an urban example,
- How a multi-risk hazard assessment can be carried out along linear infrastructure,
- How lidar can be applied in tunnelling to control and document rock properties, shotcrete and rock support,
- How terrestrial photo/lidar/radar methods can be combined for geohazard assessment and urban infrastructure settlement,
- How airborne geophysics can be used to:
- Perform soil investigations for geotechnical design of surface infrastructure,
- Find major weakness zones along tunnel alignments
- Classify hazardous quick clay
- Find the base of massive debris- and rock slides
- How geophysical and geotechnical data combine to amplify the efficiency of ground investigations
