Abstract
Artificial freezing method has been widely used in various underground projects, but the development law of melting temperature field of complex curtain is difficult to be calculated by analytical method. As a general method, numerical method is feasible to simulate the development of temperature field in horizontal melting of complex curtain. Based on the freezing construction of a subway connecting passage, this paper analyzes the law of temperature field development in the melting process, and proves the feasibility of this method by comparing with the measured data. The results can be used to guide the design and construction of artificial freezing.
