Modelling forms an implicit part of all engineering design but many engineers B~ z&
"`
are not aware either of the fact that they are making assumptions as part of IUwY/R 9Q
the modelling or of the nature and consequences of those assumptions. Many Ff|?<\x0}A
engineers make use of numerical modelling but may not have stopped to think n`CmbM@@
about the approximations and assumptions that are implicit in that modelling| _))_mxV{
still less about the nature of the constitutive models that may have been invoked. $+$+;1[
Many engineers are probably not aware of the possibilities and implications of n}a# b%e
physical modelling either at single gravity or on a centrifuge at multiple gravities. #U'n=@U@(
I have worked for many years at the interface between research and industry R D)dw
in developing numerical models of soil behaviour and in attempting to explain to W/fM0=!
practising engineers the possibilities of soil modelling. In particular, in 1996 and ~?nPp$^
1997 I held a Royal Society Industry Fellowship to be seconded to work within GAQVeL1
Babtie Group with both geotechnical and structural engineers and as a result %2V_%KA
became more aware of the realities of the conditions within typical consulting xJ,V !N
engineering companies. This book was conceived during that secondment. The mz> "4-]
scope of the book attempts to cover the range of guidance that I believe that { <&x9<f9
engineers who are undertaking geotechnical modelling need. I hope that they TMGZHO At
will ¯nd the approach accessible. c D7q;|+
Much of the material in this book has been developed during courses given to Dj?9 5Z,r
¯nal year MEng and postgraduate students at Bristol University and elsewhere. $lUZm\R|k
The reader is assumed to have a familiarity with basic soil mechanics and with <TDgv%eg0
traditional methods of geotechnical design. Some modest mathematical ability #t9&X8:U
is expected: this is not intended to deter, but rather to indicate the nature of ^m?h .
the theoretical understanding that is necessary if geotechnical modelling is to +i{&"o4}
be safely undertaken. D *heYh
My previous book Soil behaviour and critical state soil mechanics (Muir D_'Zucq
Wood, 1990) used a particular constitutive model for soil behaviour, Cam clay, KWM.b"WnXr
as a vehicle for describing the mechanical behaviour of soils and of some simple B >gC75
geotechnical structures. While Cam clay is presented brie°y in section x3.4.2, nJrV
this present book deliberately tries not to repeat too much of the material in F7a\Luae
that earlier book: there is more description of simple alternative constitutive VY vHpsI
models and of the modelling of a range of geotechnical systems. The two books `$Q
$l
should be seen as complementary. *S*;rLH9c
I am grateful to the Royal Society for the Industry Fellowship and to Babtie {DAwkJvb]
Group for welcoming me into their midst: they may not have anticipated that %]d^B |
this would have been the outcome. This book project has inevitably lingered Rg+V;C
C~
and I am grateful to Bristol University for giving me a University Research }&ZO
q'B
Fellowship during academic year 2002-2003 in order to give me slightly more xqLLoSte
time to work on the manuscript. The ¯nal surge to completion was greatly $YFn$.70\
helped by a Visiting Professorship funded by the Foundation for the Promotion d[jxU/.p;
of Industrial Science which Kazuo Konagai arranged for me at the Institute GT` :3L
of Industrial Science of the University of Tokyo. Osamu Kusakabe gave me 5 '.j+{"
particular assistance in locating references at Tokyo Institute of Technology. @eR>?.:&
Jacques Garnier, Charles Ng and Sarah Springman were also generous with !k Hpw2
information and images. GN(PH/fO9
Erdin Ibraim and Adrian Russell provided some helpful suggestions for im- XYf;72*
provement. However, the rapid march to complete the manuscript|schnell zum )R,*>-OPJL

sibility. I can only hope that the irritation attendant on their discovery will be DOf[? vbu
more than compensated by the educational bene¯t associated with the working %WdA I,
