运用ANSYS软件对深厚冲积层（厚度大于500 m)井筒冻结壁进行数值模拟，系统分析了冻结壁的最大径向位移随开挖支护段高、冲积层厚度和井帮裸露时间的变化规律，得出了最佳开挖支护段高为2 m，冲积层厚度在500 m以下的矿井壁控制在20 h以内施工完成，500 m以上的矿井壁控制在15 h以内完成。数值模拟的结果与现场实测的数据及规律相一致，比较准确地反映了现实工程状况，为类似工程施工提供参考。

The coal-shaft freezing wall (thickness greater than 500 m) was analyzed with the finite element software ANSYS. System analysis the variation of the frozen wall maximum radical displacement with high support section excavation,alluvium thickness and mine wall exposed time. Obtain the optimum height for excavation and support section 2 m and the alluvium thickness 500 m below mine wall should be completed within 20 hours while more than 500 m should be completed within 15 hours. Results of numerical simulation data and rules are consistent with field measurement results,more accurately reflects the reality for the project,and to provide a reference for similar projects.
