Definition

Adfreezing is the process by which two objects are bonded together by ice formed between them and that anchors piles or buried foundations in permafrost, so that they can be unaffected by frost heave occurring in the active layer. Adfreeze (adfreeze strength) is the shear or tensile strength that has to be overcome to separate two objects that are bonded together by ice. The shear stress required to separate an object from the frozen ground is frequently referred to as the “tangential adfreeze strength.”
