| Zusammenfassung |
| A significant open issue concerning the reliability of geophysical methods and in particular of
ground penetrating radar (GPR), both in research and professional context, is a
general lack of international standards. This is a major problem to be faced, in
order to gain scientific strictness for the GPR practices, and to easily extend to the
international community the results achieved within the area of single virtuous countries.
Producing international guidelines can represent an important step forward, in this
sense.
In the memorandum of understanding of the COST Action TU1208 is clearly stated that
one of the main purposes of the Action is the “development of innovative protocols
and guidelines which will be published in a handbook and constitute a basis for
European Standards, for an effective GPR application in CE tasks; safety, economic and
financial criteria will be integrated within the protocols”. Of course this is not a simple
task to be accomplished. Firstly, survey procedures are highly dependent on the
objective of the survey itself. On the basis of the objective of each geophysical test,
the GPR system, the antenna configuration, and even the processing procedures
may change. Besides, these procedures are also influenced by the environmental
conditions in which the tests are performed. This affects several aspects spanning from
hardware to software, but including, for instance, also safety issues. Due to these
reasons, one of the main goal of the COST Action TU1208 is the development
of several guidelines related to the main applications of GPR in the field of civil
engineering.
In this work, the structure of a guidelines handbook for GPR activities in tunnels is
outlined. In the first sections, the principal references in the field are provided, and the most
common GPR equipment and complementary technologies are described. Subsequently, the
survey methodologies are explained. Particular attention is paid to the preliminary activities
to be carried out prior to the GPR surveys, which can cover an important role in such a
complex environment. Lastly, the main applications of GPR technology in tunnels are
discussed.
