"
Reams of technical articles and
reports are produced. Both practitioners and academic researchers
have become exasperated, however, by what they perceive to be
a disappointingly small impact of that research spending on practice.
Academic researchers point their fingers at practitioners
either for being indifferent to advances in the science of geotechnical
engineering or for being unwilling to expand the effort to learn
how to use the research tools they develop. Practitioners blame
academic researchers for producing unusable, impractical, or unintelligible
research, and they identify additional obstacles to research implementation.
"
"The Transportation Research Board (TRB)
of the National Research Council annually convenes meetings for
researchers and practitioners to present and discuss research
needs and solutions in the transportation field.
Four members
of the TRB geotechnical community who have much experience in
different segments of practice and research, and who have well-informed
opinions on the problem, agreed to participate in a panel to present
their views and to motivate audience discussion.
This article
summarizes the discussion and expands upon the issues raised.
geotechnical engineering faculty more
often than not have little or no experience in practice.
As a result, they fail to understand the context into which their
research solutions must fit.
practitioners must improve their definition
of both research problem itself and the specifics of the required
research end product in a way that researchers can understand.
researchers must make more effort to understand what details
of the end product are essential to making the results valuable,
understandable, and immediately usable to the practitioner.
effective communication is the major problem.
transportation centers
are created specifically
to act as an interface between academic researchers and practitioners.
In undertaking research, engineering faculty
and their students identify a problem, they propose solutions,
they apply solution techniques, they evaluate the results, they
prepare reports, and then they present and defend those reports.
the academic system is not serving the specific research
needs of practice in most cases.
state Departments of Transportation
are ideally positioned to play a pivotal role in the research
and implementation
Their failure to take on this role adversely
impacts the implementation of research."
"Geotechnical numerical models are a case
in point of why practitioners have felt poorly served by academic
researchers.
Researchers have too often failed to deliver
numerical models that are user friendly and that take into account
the education and expertise of the likely user.
As the
design engineer considers whether or not to use the numerical
model, he or she looks next at the input parameter required to
characterize the soil at the site.
Finally, the intended
applications for the numerical model may not be clear: the specifics
of the geotechnical conditions it was intended to model may not
be well defined for the practitioner, or he or she may not understand
how to apply the results to the design itself. Practitioners and
academics agree that the cumulative result has been a disappointing
level of integration of numerical modelling into geotechnical
design."
"
A recent survey
conducted
by the ASCE Journal of Geotechnical and Geoenvironmental
Engineering to assess the interests of its readership, provides
some degree of insight into the opinions of geotechnical engineers
who read the papers written largely by researchers. ASCE received
230 replies to its survey, and 170 (74%) of those respondents
were either in private practice or in government agencies.
69% felt papers in the Journal
were too heavily biased toward theory, and 86% wanted publication
of more case histories. These figures confirm a discrepancy between
what practitioners want and what is being produced.
Practitioners
point out that this absence of practical experience among faculty
at research universities has an accompanying deleterious effect
on engineering teaching, especially in undergraduate senior design
courses mandated by ABET, and in design-oriented graduate courses.
"
"The overwhelming majority of engineering
academics wish to see their work integrated into practice, and
they often blame practitioners for being unwilling to change or
to upgrade their skills.
Nonetheless, while academics are
aware that they could do a better job with more practical experience,
the realities of their work environment in research universities
pull them in difference directions. To begin with, hiring preferences
at research universities make it clear from the outset that time
between completion of a research degree and assumption of a faculty
position is spent most advantageously in a postdoctoral position
conducting research and producing articles.
What is more,
faculty at research universities are largely discouraged from
spending time in practice during those portions of the year when
university courses are not in session.
Patterns of hires,
promotions, and raises indicate that time spent working with practitioners
is simply not viewed in itself by university administrations to
be as productive or as intellectually expanding as time spent
at the university."
"The U.S. National Science Foundation, aware
of this growing problem, developed several programs to promote
interaction of university faculty with practice, such as the GAOLI
(Grant Opportunities for Academic Liaisons with Industry) and
CAREER program.
The GAOLI program is notoriously underutilized
in the civil engineering fields, even in contrast to other fields
of engineering. And although the prestigious five-year CAREER
program is awarded in geotechnical engineering, the potential
for substantial additional funding by matching funding brought
in from industry during the award period is largely untapped in
the geotechnical program. Thus, civil engineering research faculty
are either being discouraged from acquiring themselves with the
realities of the profession they are intended to support or they
are unable to bridge the gap.
practitioners are increasingly
reluctant to commit their time, because they perceive the gap
in understanding to be too wide to bridge easily and profitably.
"
"The research valued in research university
engineering and the physical sciences programs is defined as highly
skilled specialization at the cutting edge of one's area of expertise.
Little value is placed on time spent making research results accessible
to its eventual uses.
This research evaluation template,
as it is now structured, however, is ill-suited specifically to
geotechnical and more broadly to civil engineering.
Because
it is not manufacturing-oriented, there is little potential for
significant profit deriving from research breakthroughs.
"
"
researchers often fail to meet the
needs of practitioners in the very profession they are expected
to support. To a large degree, this is a problem artificially
created by university demands on its faculty to conform to an
evaluation template ill-suited to both geotechnical and civil
engineering.
within the context of this problem, there
are working models to bridge some aspects of the gap.
as
academic credentials for geotechnical engineering practitioners
continue to rise, practitioners will be better trained, both to
use the research tools produced and to demand research products
from researchers that better suit the needs of the profession."
