Professor Jardine's recent research concerns five main areas:
Hollow Cylinder Apparatus
The Hollow Cylinder Apparatus allows exploration of 4-D stress-strain behaviour Design by Jardine (1996); see Nishimura et al and Gasparre et al.(Geotechnique February 2007) for recent application with natural London Clay.
1.Advanced Soil Testing
New and recent projects have been concerned with the advanced laboratory characterisation of natural geomaterials, using stress path triaxial, hollow cylinder, ring shear and other apparatii to investigate brittleness, sensitivity, cyclic loading response and anisotropy of strength/stiffness of geomaterials ranging from peats and sands to mudrocks and reservoir sandstones. Two curent studies include research funded by Atkins into the cyclic loading behaviour of offshore sands and studies for the PISA Wind-turbine JIP (with DONG Energy, Oxford and University College Dublin) into marine sand from Dunkerque and glacial till from Cowden in Humberside.
An associated project co-supervised with Dr C O'Sullivan concerned the simulation of Simple Shear tests by fundamental Discrete Element Method analysis.
A second ongoing research theme is the behaviour of deep foundations. A project is in progress concerning the effects of time and load cycling on the capacity of piles driven in sands, through physical model tests with highly instrumented probes. This work is being performed in conjunction with Laboratoire 3S-R of the Technical University of Grenoble, France, with funding from Total (France) and SOLCYP (France). A related study is underway in conjunction with Zheijang University China with support from the Royal Society and NSF China. The new PISA project has just commenced, which concerns field testing, analysis and design method development for laterally loaded windturbines. Other work is in progress funded by Atkins regarding foundations for offshore energy structures.
3.Soft Ground Engineering
A study is underway in conjunction with Deltares in Holland regarding flood embankment behaviour on soft organic soils. This involves a programme of full scale tests at Uitdam, north of Amsterdam, supported by other field and laboratory experiments and numerical analysis.
Several projects have been carried out over the last decade involving very large landslides that have developed off the continental shelf area in deepwater oil and gas development regions. Study areas include Ormen Lange (offshore Norway), Gulf of Mexico and deepwater Angola.
5.Geotechnical Impact of Climate Change
A final strand of recent research concerns investigating and analysing the impact of climate change on infrastructure in cold regions, focussing on potential developments in Siberia, Russia. This work progressed in conjuction with BP and UPC (Barcelona).
