摘要

Based on TOUGHREACT simulator, the mathematical model is established for representing the process of unsteady-state heat transfer between underground heat exchanger and soil water-rock-air in the infinite area. Heat transfer characteristics and distribution of transient temperature field of heat exchange wells is simulated for cooling in summer. In addition, from the statistics theory, using the statistical significance test module of SPSS software, the significance and correlation between the changes of thermo-physical parameters and temperature field of the soil are analyzed by using nonparametric Sperman rank correlation coefficient method. The practical application and design can be guided by the paper.
