摘　　要：核桃峪副井冻结深度达950 m,为世界最深的井筒冻结工程。以核桃峪副井冻结法施工为背景,考虑地层温度以及相变潜热,对井筒冻结温度场扩展规律进行数值分析,获得了冻结壁发展的相关规律,为以后类似工程提供参考。Indicates the frozen depth of auxiliary shaft at Hetaoyu reaches 950 m,which can be regarded as the deepest shaft freezing project in the world,taking the construction of the freezing method of the Hetaoyu auxiliary shaft as the background,considering the convection heat transfer,the formation temperature and the latent heat between the soil and the space,the numerical analysis of the expansion law of the freezing temperature field of the shaft is carried out,and the relevant laws of the development of the frozen wall are obtained,which will provide reference for the similar projects in the future.
