Description

TC Chair: Andrew Ridley

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.
