| Abstract: | Frozen soil has tangible rheologic characteristics. Frozen wall produces advanced displacement on the action of ground pressure, and then the rise of working surface has happened.In this paper the theoretical investigation has been made on advanced displacement and quantity of rise,and the methods of prevent working surface from rising has been discussed. |
