Abstract:
In order to clarify the impact of rainfall on the hydrothermal state within the highway subgrade in permafrost regions, a geometric similarity ratio model(1:6)of frozen subgrade was created in a baseplate-atmosphere dual-temperature control model box, based on the environmental characteristics of the Beiluhe area of the Qinghai-Xizang Plateau and the structure of frozen subgrade. First,through a comparative experiment between no rainfall and rainfall conditions, the variation characteristics of temperature and heat flux on the pavement in permafrost regions were clarified. Then, the variation characteristics of the water field and its temperature field within the highway subgrade were further explored under both conditions, and the response of the hydrothermal state within the highway subgrade in permafrost regions to rainfall was clarified. The results showthat the pavement temperature under rainfall is generally lower than that without rainfall, the heat flux at 5 cm ofthe pavement and shoulder shows a decreasing trend, and the heat flux of the pavement decreases more obviously, aboutthree times the decrease in heat flux at 5 cm of the shoulder, indicating that rainfall alleviates the heat absorption withinthe subgrade. In addition, rainfall significantly increases the shallow water content and reduces the shallow temperatureof different positions of the subgrade. Moreover, more rainfall in summer leads to more heat to be released frompermafrost subgrade, and the temperature of the subgrade decreases more obviously. However, the influence of rainfallon the water content and temperature at different depths of the subgrade gradually weakens with the increase of depth,and has little influence on the water content and temperature at 50 cm and below part of different positions of thesubgrade. In addition, compared with other positions of the subgrade, the increase of water content in the lower part ofthe natural site caused by rainfall is more obvious, while the increase of water content in the lower part of the pavementis relatively small. Although the water content in the lower part of the pavement increases less than other positions ofthe subgrade, the asphalt pavement absorbs more heat and leads to a higher temperature. Therefore, rainfall acting as anenergy cold pulse on the pavement can lead to a more significant temperature reduction. And the temperature at 5 cmbelow the pavement decreases most significantly in July, with a maximum temperature drop of 2.4 ℃.1 tab, 8 figs, 38 refs.
