摘要
基于上海市轨道交通4号线隧道修复工程实例,建立双圈水平冻结冻土帷幕温度场数值模拟模型,对实际冻结工况进行数值模拟,其结果有助于了解隧道修复冻结时冻土帷幕整体性状,确保施工安全。
Based on the Shanghai Metro Line 4 tunnel repair project, this paper establishes the numerical simulation model of temperature field of frozen soil by the artificial ground freezing with two circle horizontal tubes. Actual freezing construction conditions are simulated. The results will help recognize the overall characteristics of the frozen soil and thus ensure the safety in construction.
