摘要：
In order to explore the mechanism of salinized soil disease, the real subgrade in Hexi area, Gansu Province, China was selected and the health monitoring system of salinized soil subgrade was established. The response effect of the test system was good. In this paper, the temperature and moisture content of the system are se-lected to study the water temperature of the subgrade. The results show that the dissipation of the residual heat of the subgrade changes steadily with the seasons in winter. The distribution of subgrade moisture con-tent is affected by temperature gradient of subgrade, partition layer and pavement cover. The research results have important guiding significance for the establishment of monitoring methods of saline soil subgrade and the research on the change law of subgrade water temperature.
