Grid technique for measuring ice tunnel deformation
Butkovich, Theodore R.; Landauer, J. K. (Joseph K.)
Special ReportSummary: A new method for measuring deformation and closure of an ice tunnel has been devised. This technique requires the installation of grid lines on a smooth section of tunnel wall. Although this necessitates the work of smoothing the wall, it has the significant advantage over other methods of making the movement readily visible.
