Record #125762:

Discussion on the distribution of tangential frost-heaving force along the lateral surface of pile / Hongxu Liu.

Title: Discussion on the distribution of tangential frost-heaving force along the lateral surface of pile / Hongxu Liu.
Author(s): Liu, Hongxu.
Date: 1993.
Publisher: Wushan, Guangzhou: South China University of Technology Press
In: Permafrost. Sixth International Conference. Proceedings (Vol. 1), July 5-9, 1993, Beijing China. (1993.),
Abstract: Tests show that frost heave decreases as depth of freezing increases; stress relaxation appears to be main cause of displacement of frozen soil. Reasons not clear, but explanation is offered that, due to shrinkage caused by temperature drop, tensile strength and cracks appear later and reduce freezing strength. Tangential frost-heaving force is also reduced correspondingly.
