Abstract: In order to study the temperature field distribution law of inclined freezing shaft in water-rich sand, the paper takes a mine in Northern Shaanxi as the research background, and it’s studied by theoretical analysis, field measurement and numerical simulation. Given the mathematical model for the temperature field, and based on the superposition principle of the field given the mathematical model for the distribution of temperature field under multiple freezing pipes. The field test results of inclined freezing shaft show that: the closer to the freezing pipe, the faster of the cooling and heating speed of the freezing shaft, and the burial depth has a certain impact on the development of temperature field, but the impact is weak. It can be seen from the comparison between the numerical simulations results field measurement results that during the freezing process the variation trend of temperature is basically the same and the temperature difference of each measuring point is less than 2℃, which shows that the numerical simulation analysis of the temperature field in this paper is reliable and effective, and It can better reflect the general law of the freezing shaft with the freezing time.
