International Journal of Physical Modelling in Geotechnics contains the latest research and analysis in all areas of physical modelling at any scale, including modelling at single gravity and at multiple gravities on a centrifuge, shaking table and pressure chamber testing and geoenvironmental experiments.Topics covered: all areas of physical modelling, at any scale, including modelling at single gravity and at multiple gravities on a centrifuge, shaking table and pressure chamber testing and geoenvironmental experiments, but excluding full scale field projects unless they are part of a programme of modelling which includes tests at a smaller scale. Papers on particular instrumentation, apparatus or procedures developed for model testing and simulation of construction processes at model scale, and papers concerned with the scaling criteria for interpretation of results of model tests for application at larger scales will be welcome. The editors will be happy to advise potential authors on the acceptability of their papers for the journal.
