- Abstract
In order to study the thermodynamic effects of highway construction in plateau areas on frozen soil corridors, starting from the current practice of the frozen soil disease remediation project in plateau areas from 2017 to 2019, the mechanism of highway disease occurrence was discussed. The analysis was carried out, and the frozen soil was treated by the simulation test method. The field tests were conducted to investigate the actual use of the thermal insulation board subgrade and gravel subgrade of the diseased section. The temperature field distribution law of the frozen soil corridor project under periodic fluctuation of the boundary temperature was explored. The representative road section observation data was adopted to predict the temperature variation. Thermal characteristics of permafrost engineering corridors were analyzed. Taking the Golmud-Lhasa highway as the research object, the research results show that the construction method of the highway through the plateau directly affects the thermodynamic characteristics of the permafrost corridor project. Effective strategies have been obtained to control temperature changes, reduce roadbed damage, and enhance the thermal characteristics of permafrost engineering corridors.
