Summary: | In view of the difficulty of theoretical calculation for complex curtain with complex form of subway connecting passage freezing method, this study simulates the subway connecting passage freezing method construction with finite element method based on a practical project. The effects of different temperature cold sources, different thermal insulation materials around the subway tunnel lining, and different layout of freezing pipes on the freezing period are mainly studied. The results show that the thermal insulation materials around the subway tunnel lining have little influence on the freezing period, while the freezing cold source temperature and the arrangement of freezing pipes have great influence on the freezing period. The research content of this paper provides an effective reference for the freezing construction of subway connecting passage and an effective analysis method for designers. |
