With the increase in global temperature, the frozen soil in the Qinghai-Tibet Plateau has been degraded to varying degrees, resulting in frequent road disease in the cold area, causing the bearing capacity of the frozen soil subgrade to be attenuated. In order to study the effects of the elevated temperature on the deviatoric stress and strain of the subgrade soil, the loading rate, dynamic stress amplitude, and frequency were introduced to simulate the working conditions of the highway, which ensure the negative effect of loading rate, dynamic stress amplitude, and frequency on the deviatoric stress. Then, using the orthogonal test method, for the 9 samples make the GDS dynamic triaxial test. The test results showed that the vibration frequency is the major effect factor on the deviatoric stress, deviatoric stress increased with the vibration frequency increased; the strain increased with the loading rate increased.
