MARC recordDetermination of the undersaturation in thawed permafrost at the beginning of freezeback / O.A. Ayorinde.
| Title: | Determination of the undersaturation in thawed permafrost at the beginning of freezeback / O.A. Ayorinde. |
| Author(s): | Ayorinde, O. A. |
| Date: | 1990. |
| Publisher: | New York: American Society of Mechanical Engineers |
| In: | Proceedings of the Ninth International Conference on Offshore Mechanics and Arctic Engineering - 1990 - presented at ... Houston, Texas, February 18-23, 1990. Vol. 4. Arctic/polar technology. (1990.), |
| Abstract: | Derives mathematical relation to evaluate undersaturation at beginning of each freezeback process during several thaw-subsidence-freezeback cycles. Analysis shows how effects of initial unfrozen water content and permafrost compaction due to subsidence can be taken into account in determining freezeback pressures. Relationship for initial gas fraction is also developed which can be incorporated in freezeback model. Upper limits are established for permafrost compaction or thaw consolidation for various possible conditions. |
