摘　　要：冻土有明显的流变特性。在地压作用下，冻结壁产生超前位移，进而引起工作面的底臌。本文对超前位移及底臌进行了理论分析。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.

关 键 词：冻结井筒 超前位移 底臌 理论分析
