Interplay of Frozen Ground with Piles and Pipes During Vibratory Driving
The article deals with excavation experiments in the frozen climates of Siberia. Tests were conducted to determine the most productive method of sinking bore holes and driving piles. Three types of excavation machinery were tested: impact, vibratory-impact, and pure vibratory action. Of the three, the vibration method of pile driving was considered to be the most productive under certain permafrost conditions. Because the vibration method is able to convert mechanical energy into thermal energy, excavation in freezing temperatures is greatly facilitated. The thermal energy, which is produced predominantely at area surrounding pile point, helps to reduce resistivity of the soil and facilitates pile insertion. Additionally, a 'lubricant' (the thawing of the ice-saturated layer of frozen ground adjoining the lateral surface of the pile) produced by thermal energy decreases the amount of friction of pile against soil.
