Morning session Fraser Bransby will present work carried out at the University of Dundee on the behaviour of composite foundation systems subject to horizontal loads. Work includes investigation of skirted and piled raft foundations using centrifuge, numerical analysis and analytical modelling techniques.
Gopal Madabushi of Cambridge University will discuss insitu densification as a liquefaction resistant measure for bridge foundations. He will focus on predicting excess pore water pressure generation in loose and dense sands using a numerical modelling and experimental approach.
Jamie Standing of Imperial College will examine the effect of tunnelling on piled foundations, using the results from instrumented piles installed above Channel Tunnel Rail Link (CTRL) tunnels.
Matthew Coop and Richard Jardine will present results of research at Imperial College on advanced laboratory testing in London Clay, linking the soil's engineering behaviour to its geological origins and history. Work is based on continuous sampling and block samples from excavations for Heathrow Terminal 5.
Gilliane Sills of Oxford University will consider the cyclic behaviour of soils containing gas, with particular reference to the effect of the proportion of undissolved gas on stiffness and on cyclic failure stress levels.
Suzanne Lacasse of the Norwegian Geotechnical Institute and Professor Roger Frank of the Centre d'Enseignement et de Recherche en MÚcanique des Sols (Cermes) will close the session with a European perspective on the links between research and practice.
Their presentation will include an insight of how this link was demonstrated though the French national project on minipiles.
Afternoon session This will focus on three key construction projects with important geotechnical aspects.
Julian Crawley of Skanska Construction will present construction details and innovation at the new Stratford Station Box for CTRL.
Chris Merridew of Bachy Soletanche and Adam Chodorowski of Rail Link Engineering will discuss geotechnical work for CTRL at St Pancras Station.
The last presentation will cover the redevelopment of Battersea Power Station in London, examining, among other things, the reuse of foundations.
After coffee young engineers who have won prizes in 2005 will present their work, including Cooling Prize Winner Keith Emmet of Sheffield University, with his paper on pile disturbance in layered ground.
The afternoon session will close with the results of the BGA prediction competition including discussions of the predictions (See box for entry information).
Evening session After the agm there will be a keynote presentation on the Netherlands' National High Speed Rail Link. Hans Burger of Hoofd Integrale Veiligheid and Bob Woldringh of DHV Consultancy and Engineering will consider the significant tunnelling and embankment aspects of this scheme. This will include new options for rapid and easy construction of embankments on soft soil, results of test runs with high speed trains and details of a 6km long 15m diameter TBM tunnel.
