Robert Mair, a graduate of Cambridge studied for a PhD under the tutelage
of Professor Andrew Schofield. His interest in tunnelling and related
geotechnical research was sparked by working in Hong Kong soon after he
graduated, where he became involved in the geotechnical investigations
for the design of the new underground mass transit railway. The mechanics
of ground movements induced by tunnel construction were very much an unknown
area in those days, as were the effects of ground movements on buildings.
The development of underground mass transit systems in densely populated
cities is now becoming increasingly important, particularly because they
have the benefit of being an environmentally friendly way of getting people
around and hence are a vital part of sustainable development transport.
In
1983 with two colleagues Robert Mair set up the Geotechnical Consulting
Group (GCG) which employs highly qualified graduates, mostly from Cambridge
and Imperial College. The firm specialises in providing advice on all
matters connected with geotechnical engineering to public authorities,
contractors, and consulting engineers, principally on projects as diverse
as oil platform foundations, dam failures, and design and construction
of major tunnelling schemes. A substantial proportion of GCG's work is
overseas.
GCG has maintained close links with the universities, applying the latest
research and theories to practical situations and feeding back the results.
The use of a centrifuge to test scaled- down models has been a vital factor
in the development of soil mechanics and it has played a key role in its
application to design and construction, just as wind tunnels are used
for the study of aeronautics. Through his international consulting work
with GCG, Robert Mair has also established close working links with Japan,
which he still maintains since coming back into academia as Professor
in 1998. A number of research contracts undertaken by the Geotechnical
Research Group are supported by Japanese companies, and each year two
Cambridge undergraduates undertake their fourth year project work in Japan.
The Geotechnical Research Group now numbers around 50 researchers, about
half of whom are involved in experimental work. Robert Mair, together
with his colleagues, has recently been awarded a £2m grant from the Joint
Infrastructure Fund which will fund a new Centre for Geotechnical Process
and Construction Modelling. Construction of the new building, which will
contain experimental facilities alongside the existing Schofield Centrifuge
Centre at the West Cambridge site, begins in September.
