TC220 Field Monitoring

Field Monitoring in Geomechanics

It is well known that the real behaviour of geomechanical structures quite often differs from that predicted by numerical analyses carried out at the design stage, even though sophisticated computer programs are often used. This discrepancy may be simply because of the various uncertainties of geomaterials. In order to fill the gap between real and predicted behaviour of geomechanical structures, field monitoring is carried out to verify the input data used in the original design, as well as to assess the integrity of the structures during construction. Nowadays, there are many different monitoring techniques available. However, it should be noted that the field monitoring data are only numbers unless they are properly interpreted.

TC220 helps bring together practitioners, academics and suppliers, to exchange knowledge on field monitoring. For more information visit our website at www.field-monitoring.org and use the publications below.

Field Monitoring in Geomechanics deals with assessing the performance of engineering structures using instrumentation and other related information. The applications include dams and embankments, structures and foundations, transport infrastructure including tunnels and other underground openings,  open cut and underground mines, natural slopes, land reclamation, repositories for industrial or nuclear waste and offshore structures.

The principal aims of TC220 are:

1.       To organise specialty conferences, symposiums, workshops and short courses dedicated to the subject of field monitoring in geomechanics. To encourage the involvement of a wide range of geo-professionals in these events.

2.       To encourage the preparation of keynote lectures, state-of-the-art lectures including on new technologies, general reports for conferences organised by the International Society, regional conferences and conferences organized by Member Societies.

3.       To promote the inclusion of structural and geotechnical monitoring in universities and at conferences and meetings of other international bodies, thereby encouraging a common culture of learning through field monitoring.

FMGM is an international symposium held every four years since 1977.  TC220 will ensure that this tradition continues and will encourage ISSMGE members to participate in future FMGM Symposia.


TC220 will develop a website dedicated to field monitoring in geomechanics. This will be implemented with the support of companies involved in delivering instrumentation equipment and field monitoring services. The website will be used as a point of reference for disseminating information on monitoring best practice and as a forum for presenting case histories and lessons learned, including on-going discussion groups (blogs).

TC220 will assist with the technical programs of international and regional conferences organized by the ISSMGE.

TC220 will provide fora for all of those involved in the use of field instrumentation, such as manufacturers, installers, design consultants and owner/operators, to improve collective knowledge, support decision making and foster a common culture. This will be done mainly through FMGM Symposia and the website, but also by encouraging universities to include monitoring in curricula and by increasing field monitoring content at conferences and meetings of other international bodies.
