Use of antifriction coatings for reducing friction between pile lateral surfaces and soil
Conclusions 1. All the investigated antifriction materials substantially reduce surface friction and can be recommended for treating piles used under type II collapsibility conditions. 2. Maximum decrease in the friction (50–60% and more) is ensured by BAM-3 plastic consistent lubricant, KO-174 organosilicon enamel, profiled polyethylene, and clay and peat-clay mortars. 3. The displacement values required for total shear and for development of total friction for different antifriction materials and soil water contents vary within narrow limits and amount to about 3 mm. Changes in the water content of collapsible loess soils do not substantially affect their friction on surfaces treated with the investigated coatings.
