Abstract: Objective: To reveal the formation and development process of frozen soil can provide scientific basis for freezing method construction under complex stratigraphical conditions, thus it is necessary to study the frozen soil temperature field change law of freezing process. Method: Taking a river bottom link passage freezing engineering of Fuzhou Metro as example, soil thermophysical parameter tests and freezing temperature field tests are carried out. Values of important soil thermophysical parameters including thermal conductivity, specific heat capacity, freezing temperature are obtained through the tests, as well as the change law of the frozen soil temperature field when the freezing temperature is -5 ℃, -10 ℃, -15 ℃ and -20 ℃ respectively. Frozen soil temperature field numerical calculation analysis is carried out by ANSYS finite element calculation software, and calculation results such as freezing temperature field calculation distribution diagram, temperature distribution along path AB, average temperature of frozen soil in effective thickness range under different freezing time conditions are obtained and compared with engineering fieldmeasured values for analysis. Result & Conclusion: The lower the freezing temperature, the faster the soil temperature change rate. When the freezing temperature are -5 ℃, -10 ℃, -15 ℃, and -20 ℃, the soil temperature stable values measured by the temperature measuring hole farthest from the cold source are 0.75 ℃, -3.00 ℃, -4.00 ℃, and -7.50 ℃, respectively. The difference between the stable temperature and the corresponding freezing temperature is 5.75 ℃, 7.00 ℃, 9.00 ℃, and 12.50 ℃, respectively. In the freezing engineering, the frozen soil closing time is 30 d, active freezing time is 45 d, frozen soil average temperature reaches -14.80 ℃. The calculation results generally comply with the measurement data, errors are within the engineering allowable range, thus verifying the reliability of the proposed numerical calculation model on temperature field calculation results.
