深厚冲积层冻结壁位移场分析

On analysis of displacement field of frozen wall of deep shock layer

利用大型有限元模拟软件(ANSYS)对某矿井工程施工过程中的冻结壁位移发展及分布特点进行了分析,以井筒开挖过程中冻结壁径向位移发展规律为依据,提出了采取小段高掘砌控制冻结壁径向位移更为合理。

The paper adopts the large-scale finite elementary imitation software （ANSYS）analyzes the displacement development for the frozen wall in the engineering process and the distribution features in some mining project, and points out the adoption of the radial direction displace- ment of the frozen wall of small-section tall excavation control is more reasonable based on the development law for the radial direction of the fro- zen walls in the excavation process of the shaft project.
