Objective In order to predict the development of the frozen wall before the frozen method construction and validate the rationality of the design, providing a scientific guidance for engineering construction, it is necessary to study the temperature field development law of frozen method construction for Shanghai Metro link passages in soft soil stratum, and propose evaluation and economic indicators. Method Taking an interval of Shanghai Rail Transit Line 15 as engineering background, the frozen wall thickness, soil temperature, brine temperature, and freezing process are analyzed. A three-dimensional numerical model of the entire stratum is established using ABAQUS finite element software to predict the development characteristics of the frozen temperature field and verify it with field-measured temperature data. Result & Conclusion The average development speed of the clay layer frozen curtain is 54.535 mm/day, while the average development speed of the silty clay layer frozen curtain is 52.450 mm/da
