Mechanics of penetration of piles into permafrost
Laboratory and field tests were conducted to determine feasibility of using rockets for driving piles; field test program consisted of driving thin, hollow, full-size piles into natural permafrost using rocket as driving agent; results indicate that use of rockets is technically feasible; it is estimated that 6 in. nominal diam pile of 0.56-in. wall thickness could be driven 6 to 8 ft into permafrost by 100,000 lb thrust rocket having 80 msec burning duration; to resist collapse upon impact with permafrost, pile should have either reinforcement shoe or minimum wall thickness of 0.56 in.; design of integrated pile-rocket assembly meeting these requirements is proposed.
