| description | Moisture generation in the ventilation projects of deeply buried underground corridors affects the underground building environment and personnel health. In order to master the heat and humidity transfer law of underground corridors, this paper establishes a mathematical model by theoretical analysis, and the application of the theoretical model in engineering calculation is verified by a field test. It is found that the ventilation efficiency and heat and humidity transfer effect are related to corridor shape. The results show that under the same cross-sectional area, the average temperature drop and humidity of a rectangular corridor are 0.25% and 0.3% higher than that of an arch corridor, and 0.8% and 0.9% higher than that of a circular corridor. Under the condition of constant section circumference, the average temperature drop and humidity of a rectangular corridor are 0.51% and 0.62% higher than that of an arch corridor, and 1.37% and 1.58% higher than that of a circular corridor. When the equivalent diameter is the same, there is almost no difference in the heat and humidity transfer effect of the three shaped corridors. |
