STEPPING OUT ACROSS SIBERIA

This article draws attention to the special problems of construction in arctic conditions, particularly the problem of summer thawing of the permafrost which leads to ground heave and displaces piled foundations. An outline is presented of the method used to form structural foundations for the railway which was begun in December 1974. A deep hole is drilled into the ground, a prefabricated ferro-concrete pile is lowered into it, and concrete is poured into the narrow free space remaining inbetween. The concrete forms a strong bond between the pile and the surrounding, still-frozen soil. However, larger structures require far more extensive foundation works with subsequent subsidence problems if undertaken during the summer season. Mention is made of the use of refrigeration piles, and of the hydraulic method of transport of the ballast required for the project. /TRRL/
