地层冻结法在我国应用已超过60年。作为地下工程和隧道工程治水最有效方法之一，既有它的优势也存在一定的风险。给出冻结工程的全过程流程，并从冻土结构在施工过程中受力机制分为“隔水”（水压）和“既隔水又承受岩土压”（土水压）之间的差异，详尽说明需要考虑的影响设计的主要因素，特别对地层冻胀和融沉机制和预防做出详细阐述，最后给出在隧道工程的地层冻结方面的最新进展。

Artificial ground freezing method has been applied in China for more than 60 years. As one of the most effective methods for controlling water in the underground works and tunnel works, artificial ground freezing method has its advantages and risks. In the paper, the procedure of artificial ground freezing is presented, the factors that should be considered in the design of artificial ground freezing are discussed, the mechanism of frost heaving and thaw settlement, as well as the prevention measures, are expounded, and the progress of artificial ground freezing method applied in tunel works are provided.
