以上海某地铁出入口冻结法施工为例，结合数值模拟分析，总结了冻结法在浅埋暗挖工程中应用的关键技术措施，主要包括冻结壁安全措施、冻胀与融沉控制、信息化监测等，为冻结法施工积累了经验。%Take the freezing construction of a subway passageway in Shanghai as an example,combining with the numerical simulation analysis, this article analyze and summarize the key technical measures of the freezing construction application in the shallow covered excavation construc-tion. The content includes the control of the freezing wall extending area,the control of frost heaving and thawing settlement,and the informative monitoring,which has accumulated experience for freezing construction.
