| Abstract: | It is shown by experimence that when specimen with varios size and shape cut from building brick was frozen in water and then was thawn one-dimentionally downword, water flowed through brick to the interface between ice and brick and frozen there, causing heave and sample moved up. Analoguous process might occur during the thawing of permafrost in the summer and accamulating rate of ice is accelerated near permafrost table. |
