Datasets description

 This data set has carried out many field investigations on the subgrade crack damage in the section K2900~K3400 of the Qinghai Tibet Highway from March 2014 to November 2017. 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.
