'CHALLENGES OF environmental geotechnics' is the title of this year's Rankine Lecture, to be held at Imperial College next month.
Professor Heinz Brandl from the Technical University of Vienna, Austria, will discuss environmental geotechnics in a wide context, including geothermal energy extraction from foundations, retaining structures, tunnels and roads.
The second part of his lecture will focus on landfill engineering including general aspects of waste management. He will discuss multi-barrier systems, continuous compaction control of clay liners, cut-off walls with an inverse hydraulic gradient and the use of geosynthetics.
In his discussion of 'green' retaining structures, especially crib walls and pier walls on unstable slopes, Brandl will present results of long-term monitoring, including earth pressure redistribution in the case of prestressed anchors and soil pressure within modular crib walls.
Brandl is the foremost academic in geotechnical engineering in Austria and is widely consulted on many projects. His research has concentrated on applied ground engineering in a wide variety of areas including soil stabilisation, slope stability, retaining structures, foundations and environmental geotechnics. He has published several hundred papers and 15 books.
He has also worked extensively in practice, where he has been responsible for the geotechnical aspects of numerous projects including transport infrastructure, underground construction, dams, remediation and use of geothermal energy.
This year's Rankine Lecture is on 21 March at Imperial College, London at 5.30pm. It is followed by a reception and dinner.
