The investigation contents include subgrade height, road direction, crack width and length, subgrade melting settlement, etc. The distribution characteristics of subgrade cracks of the Qinghai Tibet Highway are obtained through the summary and analysis of the investigation. The trend of the road, the maximum width of the subgrade crack and the differential settlement of the pavement are mainly analyzed. It is found that the maximum width of the crack reaches 37 cm at the K3330 section near the Tanggula mountain area.
