Soviet know-how copes with permafrost
Layer thicknesses vary from several feet to half-mile; 40-in. thick "active" layer melts in summer with temperatures of 17 to 19 F found, being warmer than assumed; action of "active" layer caused bulging now overcome by reinforcing of foundations on apartment buildings and formula for pile length being twice as deep into permafrost layer as thickness of active layer, with as much ventilated air space above as thickness of active layer; experiments for heavy construction foundations are with air blanket and heating of foundations utilizing excellent electric conductivity of permafrost zone.
