| Description: | Technical Report Summary: A timber pile foundation was installed in permafrost at Kotzebue, Alaska, as part of the construction of an Air Force Installation in 1955 and 1956. The piles were placed in augered holes, slurried and frozen back by artificial means. Data were obtained on the effectiveness of the artificial refrigeration in achieving freezeback and on the bearing capacity of the piles. Soil temperatures were measured with copper constantan thermocouples. Fiberglass moisture cells were also tried. Level observations were made on the piling to detect heave and settlement. Two types of pile load tests were conducted; point bearing tests on piles confined by small amounts of unfrozen soil, and load settlement tests on piles completely slurried and frozen back. |
