Preliminary Assessment of a Friction-Sleeve-Equipped Minipenetrometer
Publication: Journal of Cold Regions Engineering
Volume 31, Issue 2
Abstract
A hand-driven friction-sleeve-equipped minipenetrometer was assessed for its efficacy in determining snow physical properties. Numerous factors were investigated including the effect of penetration rate, penetrometer effective diameter, compaction ahead of the penetrometer, distance for representative resistance to be mobilized, and the effect of snow density on penetrometer tip resistance and sleeve friction. Analysis suggests that consideration of additional friction-sleeve data may provide greater insight into snow physical properties compared to consideration of tip-resistance data alone. A friction-sleeve-equipped penetrometer provides valuable data in snow and firn beyond that obtainable through the use of a device measuring only penetrative resistance at the tip.
