摘要：The freezing method is often used in underground excavation projects with high requirements for water stop and support. However, with the increasing complexity of the project, the freezing form is becoming more and more complex, and it is difficult to calculate the temperature field law by theoretical analysis. As a powerful simulation method, numerical calculation can be used to simulate the development of temperature field in complex horizontal freezing engineering. Based on the horizontal freezing construction of a subway connecting passage, this paper analyzes the development characteristics of horizontal freezing temperature field, and the results are in good agreement with the measured data. It is proved that the numerical simulation method can be used to simulate this kind of project, and the results can be used to guide the design and construction of related projects.
