Experimental Study on Frost-Heaving Force Development of Tibetan Clay Subjected to One-Directional Freezing in an Open System

open access: yesAdvances in Civil Engineering, 2021
Frost heave of soils involves complex coupled interactions among moisture, heat, and stress, which can cause serious damage to cold regions engineering. In this paper, a series of one-directional freezing experiments were implemented for the Tibetan clay

Frost-Heaved Bedrock Features: A Valuable Permafrost Indicator [PDF]

open access: yes, 1983
Frost-heaved bedrock features are periglacial forms produced by the vertical displacement of bedrock fragments. Blocks, frost-wedged from bare bedrock along joints, are raised above the general surface by heave.

Thermal modeling of Anchorage driveway culvert with addition of insulation to prevent frost heaving [PDF]

open access: yes, 2017
A predominate problem in cold regions, and specifically in Anchorage, Alaska, is frost heaving pavement above culverts in residential driveways. The culvert increases heat loss in the subgrade materials during winter months and allows the soils below ...
