Abstract
Time-domain reflectometry is an electromagnetic pulse technique that has been used to measure the dielectric constant of soils at frequencies between 1MHz and 1GHz. The dielectric constant of water is 30 times that of ice, making it possible to delineate the freezing front in soils. Results of laboratory experiments will be presented to show the application of this technique to determine the thickness of the frozen zone in coarse-grained and fine-grained soils. The location of the freezing boundary using time- domain reflectometry will be compared with temperature measurements and interpretations from X-ray photographs.
